Merge additional ACPI device enumeration code changes for 6.5-rc1.

 - Make acpi_companion_match() return a const pointer and update its
   callers accordingly (Andy Shevchenko).

 - Move the extern declaration of the acpi_root variable to a header
   file so as to address a compiler warning (Andy Shevchenko).

 - Address compiler warnings in the ACPI device enumeration code by
   adding a missing header file include to it (Ben Dooks).

 - Refine the SMB0001 quirk in the ACPI device enumeration code so as to
   address an i2c-scmi driver regression (Andy Shevchenko).

 - Clean up two pieces of the ACPI device enumeration code (Andy
   Shevchenko).

* acpi-bus:
  ACPI: bus: Constify acpi_companion_match() returned value

* acpi-scan:
  ACPI: scan: Use the acpi_match_acpi_device() helper
  ACPI: platform: Move SMB0001 HID to the header and reuse
  ACPI: platform: Ignore SMB0001 only when it has resources
  ACPI: bus: Introduce acpi_match_acpi_device() helper
  ACPI: scan: fix undeclared variable warnings by including sleep.h
  ACPI: scan: Move acpi_root to internal header

Match the ACPI device against a given list of ACPI IDs.

Subsequent changes will make use of this.

acpi_companion_match() doesn't alter the contents of the passed
parameter, so we don't expect that returned value can be altered
either. So constify it.

Pull ACPI updates from Rafael Wysocki:
 "These rework the handling of notifications in ACPI button drivers (to
  enable future simplifications and cleanups), clean up the ACPI thermal
  driver, update the ACPI backlight driver, add quirks working around
  AML bugs on some systems, fix some assorted issues and clean up code.

  Specifics:

   - Reduce ACPI device enumeration overhead related to devices with
     dependencies (Rafael Wysocki)

   - Fix the handling of Microsoft LPS0 _DSM for suspend-to-idle (Mario
     Limonciello)

   - Fix section mismatch warning in the ACPI suspend-to-idle code (Arnd
     Bergmann)

   - Drop several ACPI resource management quirks related to IRQ
     ovverides on AMD "Zen" systems (Mario Limonciello)

   - Modify the ACPI EC driver to make it only clear the EC GPE status
     when handling the GPE (Jeremy Compostella)

   - Add quirks to work around ACPI tables defects on Lenovo Yoga Book
     yb1-x90f/l and Nextbook Ares 8A (Hans de Goede)

   - Add ACPi backlight quirks for Dell Studio 1569, Lenovo ThinkPad
     X131e (3371 AMD version) and Apple iMac11,3 and stop trying to use
     vendor backlight control on relatively recent systems (Hans de
     Goede)

   - Add pwm_lookup_table entry for second PWM on CHT/BSW devices in the
     ACPI LPSS (Intel SoC) driver (Hans de Goede)

   - Add nfit_intel_shutdown_status() declaration to a local header to
     avoid a "missing prototypes" build warning (Arnd Bergmann)

   - Clean up the ACPI thermal driver and drop some dead or otherwise
     unneded code from it (Rafael Wysocki)

   - Rework the handling of notifications in the ACPI button drivers so
     as to allow the common notification handling code for devices to be
     simplified (Rafael Wysocki)

   - Make ghes_get_devices() return NULL to indicate that there are no
     GHES devices so as to allow vendor-specific EDAC drivers to probe
     then (Li Yang)

   - Mark bert_disable() as __initdata and drop an unused function from
     the APEI GHES code (Miaohe Lin)

   - Make the ACPI PAD (Processor Aggregator Device) driver realize that
     Zhaoxin CPUs support nonstop TSC (Tony W Wang-oc)

   - Drop the certainly unnecessary and likely incorrect inclusion of
     linux/arm-smccc.h from acpi_ffh.c (Sudeep Holla)"

  ACPI: PAD: mark Zhaoxin CPUs NONSTOP TSC correctly
  ACPI: APEI: mark bert_disable as __initdata
  ACPI: EC: Clear GPE on interrupt handling only

  ACPI: x86: s2idle: Adjust Microsoft LPS0 _DSM handling sequence
  ACPI: resource: Remove "Zen" specific match and quirks
  ...

Because the only drivers that cared about button fixed events take care
of those events by themselves now, eliminate the code related to them
from acpi_device_install_notify_handler() and
acpi_device_remove_notify_handler().

Move all of the ARM-specific initialization into one function namely
acpi_arm_init(), so it is not necessary to modify/update bus.c every
time a new piece of it is added.

Pull char/misc drivers updates from Greg KH:
 "Here is the "big" set of char/misc and other driver subsystems for
  6.4-rc1.

  It's pretty big, but due to the removal of pcmcia drivers, almost
  breaks even for number of lines added vs. removed, a nice change.

  Included in here are:

   - removal of unused PCMCIA drivers (finally!)

   - Interconnect driver updates and additions

   - Lots of IIO driver updates and additions

   - MHI driver updates

   - Coresight driver updates

   - NVMEM driver updates, which required some OF updates

   - W1 driver updates and a new maintainer to manage the subsystem

   - FPGA driver updates

   - New driver subsystem, CDX, for AMD systems

   - lots of other small driver updates and additions

  All of these have been in linux-next for a while with no reported
  issues"

Currently, acpi_device_remove_notify_handler() may return while the
notify handler being removed is still running which may allow the
module holding that handler to be torn down prematurely.

Address this issue by making acpi_device_remove_notify_handler() wait
for the handling of all the ACPI events in progress to complete before
returning.
