ACPI updates for 6.6-rc1

Browse Source 
- Update the ACPICA code in the kernel to upstream revision 20230628
    including the following changes:
    * Suppress a GCC 12 dangling-pointer warning (Philip Prindeville).
    * Reformat the ACPI_STATE_COMMON macro and its users (George Guo).
    * Replace the ternary operator with ACPI_MIN() (Jiangshan Yi).
    * Add support for _DSC as per ACPI 6.5 (Saket Dumbre).
    * Remove a duplicate macro from zephyr header (Najumon B.A).
    * Add data structures for GED and _EVT tracking (Jose Marinho).
    * Fix misspelled CDAT DSMAS define (Dave Jiang).
    * Simplify an error message in acpi_ds_result_push() (Christophe
      Jaillet).
    * Add a struct size macro related to SRAT (Dave Jiang).
    * Add AML_NO_OPERAND_RESOLVE flag to Timer (Abhishek Mainkar).
    * Add support for RISC-V external interrupt controllers in MADT (Sunil
      V L).
    * Add RHCT flags, CMO and MMU nodes (Sunil V L).
    * Change ACPICA version to 20230628 (Bob Moore).
 
  - Introduce new wrappers for ACPICA notify handler install/remove and
    convert multiple drivers to using their own Notify() handlers instead
    of the ACPI bus type .notify() slated for removal (Michal Wilczynski).
 
  - Add backlight=native DMI quirk for Apple iMac12,1 and iMac12,2 (Hans
    de Goede).
 
  - Put ACPI video and its child devices explicitly into D0 on boot to
    avoid platform firmware confusion (Kai-Heng Feng).
 
  - Add backlight=native DMI quirk for Lenovo Ideapad Z470 (Jiri Slaby).
 
  - Support obtaining physical CPU ID from MADT on LoongArch (Bibo Mao).
 
  - Convert ACPI CPU initialization to using _OSC instead of _PDC that
    has been depreceted since 2018 and dropped from the specification in
    ACPI 6.5 (Michal Wilczynski, Rafael Wysocki).
 
  - Drop non-functional nocrt parameter from ACPI thermal (Mario
    Limonciello).
 
  - Clean up the ACPI thermal driver, rework the handling of firmware
    notifications in it and make it provide a table of generic trip point
    structures to the core during initialization (Rafael Wysocki).
 
  - 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).
 
  - Fix and clean up suspend-to-idle interface for AMD systems (Mario
    Limonciello, Andy Shevchenko).
 
  - Fix string truncation warning in pnpacpi_add_device() (Sunil V L).

Merge tag 'acpi-6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These include new ACPICA material, a rework of the ACPI thermal
  driver, a switch-over of the ACPI processor driver to using _OSC
  instead of (long deprecated) _PDC for CPU initialization, a rework of
  firmware notifications handling in several drivers, fixes and cleanups
  for suspend-to-idle handling on AMD systems, ACPI backlight driver
  updates and more.
