The Surface System Aggregator Module (SSAM) has multiple subsystems that
can manage detachable devices. At the moment, we only support the "base"
(BAS/0x11) subsystem, which is used on the Surface Book 3 to manage
devices (including keyboard, touchpad, and secondary battery) connected
to the base of the device.
The Surface Pro 8 has a new type-cover with keyboard and touchpad, which
is managed via the KIP/0x0e subsystem. The general procedure is the
same, but with slightly different events and setup. To make
implementation of the KIP hub easier and prevent duplication, generify
the parts of the base hub that we can use for the KIP hub (or any
potential future subsystem hubs).
This also switches over to use the newly introduced "hot-remove"
functionality, which should prevent communication issues when devices
have been detached.
Lastly, also drop the undocumented and unused sysfs "state" attribute of
the base hub. It has at best been useful for debugging.

When SSAM client devices have been (physically) hot-removed,
communication attempts with those devices may fail and time out. This
can even extend to event notifiers, due to which timeouts may occur
during device removal, slowing down that process.
Add a parameter to the notifier unregister function that allows skipping
communication with the EC to prevent this. Furthermore, add wrappers for
registering and unregistering notifiers belonging to SSAM client devices
that automatically check if the device has been marked as hot-removed
and communication should be avoided.
Note that non-SSAM client devices can generally not be hot-removed, so
also add a convenience wrapper for those, defaulting to allow
communication.

The def_bool y PMC_ATOM Kconfig option provides a couple of symbols used
by the code enabled by the X86_INTEL_LPSS option and it registers some
clocks. These clocks are only registered on Bay Trail, Cherry Trail and
Brasswell Intel SoCs and kernels targeting these SoCs must always have
the X86_INTEL_LPSS option enabled otherwise many things will not work.
Building the PMC_ATOM code on kernels which are not targeting the
mentioned SoCs and which do not have the X86_INTEL_LPSS enabled is
not useful.
This means that we can simplify things by replacing the PMC_ATOM Kconfig
option in Makefiles with X86_INTEL_LPSS and then drop the option.

WMI queries fail on some devices where the ACPI method HWMC
unconditionally attempts to create Fields beyond the buffer
if the buffer is too small, this breaks essential features
such as power profiles:
CreateByteField (Arg1, 0x10, D008)
CreateByteField (Arg1, 0x11, D009)
CreateByteField (Arg1, 0x12, D010)
CreateDWordField (Arg1, 0x10, D032)
CreateField (Arg1, 0x80, 0x0400, D128)
In cases where args->data had zero length, ACPI BIOS Error
(bug): AE_AML_BUFFER_LIMIT, Field [D008] at bit
offset/length 128/8 exceeds size of target Buffer (128 bits)
(20211217/dsopcode-198) was obtained.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [D009] at bit
offset/length 136/8 exceeds size of target Buffer (136bits)
(20211217/dsopcode-198)
The original code created a buffer size of 128 bytes regardless if
the WMI call required a smaller buffer or not. This particular
behavior occurs in older BIOS and reproduced in OMEN laptops. Newer
BIOS handles buffer sizes properly and meets the latest specification
requirements. This is the reason why testing with a dynamically
allocated buffer did not uncover any failures with the test systems at
hand.
This patch was tested on several OMEN, Elite, and Zbooks. It was
confirmed the patch resolves HPWMI_FAN GET/SET calls in an OMEN
Laptop 15-ek0xxx. No problems were reported when testing on several Elite
and Zbooks notebooks.

The driver is using functions from a compilation unit which is enabled
by CONFIG_CPU_SUP_INTEL. Add that dependency to Kconfig explicitly
otherwise:
drivers/platform/x86/intel/ifs/load.o: in function `ifs_load_firmware':
load.c:(.text+0x3b8): undefined reference to `intel_cpu_collect_info'
