Merge ACPI device enumeration changes, ACPI TAD and extlog drivers
updates, and miscellaneous ACPI-related changes for 6.6-rc1:

 - Defer enumeration of devices with _DEP pointing to IVSC (Wentong Wu).

 - Install SystemCMOS address space handler for ACPI000E (TAD) to meet
   platform firmware expectations on some platforms (Zhang Rui).

 - Fix finding the generic error data in the ACPi extlog driver for
   compatibility with old and new firmware interface versions (Xiaochun
   Lee).

 - Remove assorted unused declarations of functions (Yue Haibing).

 - Move AMBA bus scan handling into arm64 specific directory (Sudeep
   Holla).

* acpi-scan:
  ACPI: scan: Defer enumeration of devices with a _DEP pointing to IVSC device

* acpi-tad:
  ACPI: TAD: Install SystemCMOS address space handler for ACPI000E

* acpi-extlog:
  ACPI: extlog: Fix finding the generic error data for v3 structure

* acpi-misc:
  ACPI: Remove assorted unused declarations of functions
  ACPI: Remove unused extern declaration acpi_paddr_to_node()
  ACPI: Move AMBA bus scan handling into arm64 specific directory

acpi_create_dir()/acpi_remove_dir() are never implemented since
the beginning of git history.

Commit f8d31489629c ("ACPICA: Debugger: Convert some mechanisms to OSPM specific")
declared but never implemented acpi_run_debugger().

Commit 781d737c7466 ("ACPI: Drop power resources driver")
removed acpi_power_init() but not its declaration.

Commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific
initialisation into acpi_arm_init()") moved all of the ARM-specific
initialization into acpi_arm_init(). However, acpi_amba.c being outside
of drivers/acpi/arm64 got ignored and hence acpi_amba_init() was not
moved into acpi_arm_init().

Move the AMBA platform bus support into arm64 specific folder and make
acpi_amba_init() part of acpi_arm_init().

Change acpi_early_processor_osc() to return a value in case of a
failure and make it static.

Also make it run acpi_processor_osc() for every processor object or
processor device found in the ACPI Namespace (previously, its only purpose
was to work around platform firmware defects on Skylake systems).

Introduce a new function called acpi_early_processor_control_setup() that
will invoke acpi_early_processor_osc() first in order to convey the OS
processor support information to the platform firmware and if that fails,
it will fall back to using _PDC.

Since _PDC method is deprecated and a preferred method of communicating
OSPM processor power management capabilities is _OSC, there is a need to
move function checking whether processor is present as this logic is not
_PDC specific.

Move processor_physically_present() to acpi_processor.c.

No intentional functional impact.

Commit 2a2a64714d9c ("ACPI: Disable MWAIT via DMI on broken Compal board")
introduced a workaround for MWAIT for a specific x86 system.

Move the code outside of acpi_processor.c to acpi/x86/ directory for
consistency and rename the functions associated with it, so their names
start with "acpi_proc_quirk_" to make the goal obvious.

No intentional functional impact.

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

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.

Compiler is not happy about handling of acpi_root variable:

  ...drivers/acpi/bus.c:37:20: warning: symbol 'acpi_root' was not declared. Should it be static?

Move it's definition to the internal header.

The uevent() callback in struct device_type should not be modifying the
device that is passed into it, so mark it as a const * and propagate the
function signature changes out into all relevant subsystems that use
this callback.
