Scan image loading flow for newer IFS generations are slightly different

done once for each socket as was done in gen0.
Also the width of NUM_CHUNKS bitfield in SCAN_HASHES_STATUS MSR has

CHUNK_AUTHENTICATION_STATUS too.
Further the parameter to AUTHENTICATE_AND_COPY_CHUNK is passed

The hardware definition of every TPMI feature contains a major and minor
version. When there is a change in the MMIO offset or change in the
definition of a field, hardware will change major version. For addition
of new fields without modifying existing MMIO offsets or fields, only the
minor version is changed.
Driver is developed to support uncore frequency control (UFS) for a major
and minor version. If the hardware changes major version, since offsets
and definitions are changed, driver cannot continue to provide UFS
interface to users. Driver can still function with minor version change
as it will just miss the new functionality added by the hardware.
The current implementation logs information message and skips adding
uncore sysfs entry for a resource for any version mismatch. Check major
and minor version mismatch for every valid resource and fail on any major
version mismatch by logging an error message. A valid resource has a
version which is not 0xFF.
If there is mismatch with the minor version, continue with a log message.

Allowed level mask is a mask of levels, which are currently allowed to
dynamically switch by the OS. Fused mask is a mask of all levels even if
OS is not allowed to switch.
Even if OS is not allowed to dynamically switch, it is still possible for
user to boot to a level by using BIOS option. To decide which level to
boot next time, user wants to check parameters (power, performance or
thermal) of that level to decide.
So, when passing the level mask for display to user space, use fuse
enabled mask, which has all levels.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Pull x86 microcode loading updates from Borislav Petkov:
"The first, cleanup part of the microcode loader reorg tglx has been
working on. The other part wasn't fully ready in time so it will
follow on later.
This part makes the loader core code as it is practically enabled on
pretty much every baremetal machine so there's no need to have the
Kconfig items.
In addition, there are cleanups which prepare for future feature
enablement"

HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS
method. If VGBS is not called on boot, the firmware sends an initial
0xcd event shortly after calling the BTNL method, but only if the device
is booted in the laptop mode. However, if the device is booted in the
tablet mode and VGBS is not called, there is no initial 0xcc event, and
the input device for SW_TABLET_MODE is not registered up until the user
turns the device into the laptop mode.
Call VGBS on boot on this device to get the initial state of
SW_TABLET_MODE in a reliable way.
Tested with BIOS 1.13.1.

On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE
are only send after the BTNL ACPI method has been called.
Likely more devices need this, so make the BTNL ACPI method unconditional
instead of only doing it on devices with a 5 button array.
Note this also makes the intel_button_array_enable() call in probe()
unconditional, that function does its own priv->array check. This makes
the intel_button_array_enable() call in probe() consistent with the calls
done on suspend/resume which also rely on the priv->array check inside
the function.

cap_offset is a u16 field, so multiplying with TPMI_CAP_OFFSET_UNIT
(which is equal to 1024) to covert to bytes will cause overflow. This
will be a problem once more TPMI features are added.
This field is not used except for calculating pfs->vsec_offset. So, leave
cap_offset field unchanged and multiply with TPMI_CAP_OFFSET_UNIT while
calculating pfs->vsec_offset.
