We don't have a running VCPU context to restore vgic3 LPI pending status
due to command KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_RESTORE_TABLES} on KVM
device "kvm-arm-vgic-its".
Use vgic_write_guest_lock() to restore vgic3 LPI pending status.

Currently, the unknown no-running-vcpu sites are reported when a
dirty page is tracked by mark_page_dirty_in_slot(). Until now, the
only known no-running-vcpu site is saving vgic/its tables through
KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_SAVE_TABLES} command on KVM device
"kvm-arm-vgic-its". Unfortunately, there are more unknown sites to
be handled and no-running-vcpu context will be allowed in these
sites: (1) KVM_DEV_ARM_{VGIC_GRP_CTRL, ITS_RESTORE_TABLES} command
on KVM device "kvm-arm-vgic-its" to restore vgic/its tables. The
vgic3 LPI pending status could be restored. (2) Save vgic3 pending
table through KVM_DEV_ARM_{VGIC_GRP_CTRL, VGIC_SAVE_PENDING_TABLES}
command on KVM device "kvm-arm-vgic-v3".
In order to handle those unknown cases, we need a unified helper
vgic_write_guest_lock(). struct vgic_dist::save_its_tables_in_progress
is also renamed to struct vgic_dist::save_tables_in_progress.
No functional change intended.

With module and carrier board topology, carrier board dts will include
module dtsi files for creating complete platform.
The carrier board dts will have final model name and compatible string
so any model name added in module dtsi will eventually replaced.
This happened for any devicetree property if the same property is updated
or added twice.
So, drop this unneeded model name from module dtsi.

Currently dump_kernel_instr() dumps a few instructions around the
pt_regs::pc value, dumping 4 instructions before the PC before dumping
the instruction at the PC. If an attempt to read an instruction fails,
it gives up and does not attempt to dump any subsequent instructions.
This is unfortunate when the pt_regs::pc value points to the start of a
page with a leading guard page, where the instruction at the PC can be
read, but prior instructions cannot.
This patch makes dump_kernel_instr() attempt to dump each instruction
regardless of whether reading a prior instruction could be read, which
gives a more useful code dump in such cases. When an instruction cannot
be read, it is reported as "????????", which cannot be confused with a
hex value,
For example, with a `UDF #0` (AKA 0x00000000) early in the kexec control
page, we'll now get the following code dump:

Currently we rely on the HIBERNATE_TEXT section starting with the entry
point to swsusp_arch_suspend_exit, and the KEXEC_TEXT section starting
with the entry point to arm64_relocate_new_kernel. In both cases we copy
the entire section into a dynamically-allocated page, and then later
branch to the start of this page.
SYM_FUNC_START() will align the function entry points to
CONFIG_FUNCTION_ALIGNMENT, and when the linker later processes the
assembled code it will place padding bytes before the function entry
point if the location counter was not already sufficiently aligned. The
linker happens to use the value zero for these padding bytes.
This padding may end up being applied whenever CONFIG_FUNCTION_ALIGNMENT
is greater than 4, which can be the case with
CONFIG_DEBUG_FORCE_FUNCTION_ALIGN_64B=y or
CONFIG_DYNAMIC_FTRACE_WITH_CALL_OPS=y.
When such padding is applied, attempting to kexec or resume from
hibernate will result ina crash: the kernel will branch to the padding
bytes as the start of the dynamically-allocated page, and as those bytes
are zero they will decode as UDF #0, which reliably triggers an
UNDEFINED exception. For example:

Note: Unfortunately the code dump reports "bad PC value" as it attempts
to dump some instructions prior to the UDF (i.e. before the start of the
page), and terminates early upon a fault, obscuring the problem.
This patch fixes this issue by aligning the section starter markes to
CONFIG_FUNCTION_ALIGNMENT using the ALIGN_FUNCTION() helper, which
ensures that the linker never needs to place padding bytes within the
section. Assertions are added to verify each section begins with the
function we expect, making our implicit requirement explicit.
In future it might be nice to rework the kexec and hibernation code to
decouple the section start from the entry point, but that involves much
more significant changes that come with a higher risk of error, so I've
tried to keep this fix as simple as possible for now.

For proper warm (re)boot from SD card the BPI-M5 board requires TFLASH_VDD_EN
and VDDIO_C pins to be switched to high impedance mode. This can be achieved
using OPEN_DRAIN instead of ACTIVE_HIGH to leave the GPIO pins in input mode
and retain high state (pin has the pull-up).
This change is inspired by meson-sm1-odroid.dtsi where OPEN_DRAIN has been
used to resolve similar problems with the Odroid C4 board (TF_IO in the C4
dts is the equivalent regulator).

The RZ/V2M EVK uses the PWC IP to control external power supplies
and the I/O voltage for the uSD card.
This patch enables the PWC node, and it also enables the poweroff
features since PWC is actually used to control the board power
rails.

The RZ/V2M SoC contains an External Power Sequence Controller (PWC)
module. This module provides an external power supply on/off
sequence, on/off signal for the LPDDR4 core power supply, General
Purpose Outputs, and key input signals.
This patch adds PWC support to the SoC specific device tree.

Although of_fdt_device_is_available returns true when the DT
property "status" is assigned "ok" or "okay", and false for every
other value, it's become common practice to assign "disabled"
when we want of_fdt_device_is_available to return false.
For some reason, the status property of the ethernet node was
assigned "disable" when originally added to the kernel. Change
it to "disabled" for consistency.

The WM8962 is configured so the SoC is driving the clock, and it's
currently set to 24 MHz. However, when playing audio it shows the
following message:
wm8962 5-001a: Unsupported sysclk ratio 500
While not harmful, a better clock ratio is 512. It makes the
message disappear, and it still plays sound.

Due to the part shortage, the AR8031 PHY was replaced with a Micrel
KSZ9131. Hard-coding the ID of the PHY makes this new PHY
non-operational on newer hardware. Since previous hardware had only
shipped to a limited number of people, and they have not gone to
production, it should be safe to update the PHY ID.

The board used to originally introduce the Beacon Embedded RZ/G2[M/N/H]
boards had a GPIO expander with address 20, but this was changed when
the final board went to production.
The production boards changed both the part itself and the address.
With the incorrect address, the LCD cannot come up. If the LCD fails,
the rcar-du driver fails to come up, and that also breaks HDMI.
Pre-release board were not shipped to the general public, so it should
be safe to push this as a fix. Anyone with a production board would
have video fail due to this GPIO expander change.

Enable UFS device for R-Car S4-8 Spider CPU board.
Note that the conditions of RC21012 on the Spider are:
- OUT11 (for UFS30_REFCLK_V) is disabled as default.
- OUT11 is controlled by GPIO0 pin.
- The GPIO0 pin is inverted sense (low active) and pull-up enabled.
To output the clock, pin 4 of TCA9554 on the Spider board needs to
output low level so that using "gpio-gate-clock" for it.
