ACPI updates for 6.13-rc1

Browse Source 
- Fix _CPC register setting issue for registers located in memory in
    the ACPI CPPC library code (Lifeng Zheng).
 
  - Use DEFINE_SIMPLE_DEV_PM_OPS in the ACPI battery driver, make it use
    devm_ for initializing mutexes and allocating driver data, and make
    it check the register_pm_notifier() return value (Thomas Weißschuh,
    Andy Shevchenko).
 
  - Make the ACPI EC driver support compile-time conditional and allow
    ACPI to be built without CONFIG_HAS_IOPORT (Arnd Bergmann).
 
  - Remove a redundant error check from the pfr_telemetry driver (Colin
    Ian King).
 
  - Rearrange the processor_perflib code in the ACPI processor driver
    to avoid compiling x86-specific code on other architectures (Arnd
    Bergmann).
 
  - Add adev NULL check to acpi_quirk_skip_serdev_enumeration() and
    make UART skip quirks work on PCI UARTs without an UID (Hans de
    Goede).
 
  - Force native backlight handling Apple MacbookPro11,2 and Air7,2 in
    the ACPI video driver (Jonathan Denose).
 
  - Switch several ACPI platform drivers back to using struct
    platform_driver::remove() (Uwe Kleine-König).
 
  - Replace strcpy() with strscpy() in multiple places in the ACPI
    subsystem (Muhammad Qasim Abdul Majeed, Abdul Rahim).

Pull ACPI updates from Rafael Wysocki:
 "These include a couple of fixes, a new ACPI backlight quirk for Apple
  MacbookPro11,2 and Air7,2 and a bunch of cleanups:

   - Fix _CPC register setting issue for registers located in memory in
     the ACPI CPPC library code (Lifeng Zheng)

   - Use DEFINE_SIMPLE_DEV_PM_OPS in the ACPI battery driver, make it
     use devm_ for initializing mutexes and allocating driver data, and
     make it check the register_pm_notifier() return value (Thomas
     Weißschuh, Andy Shevchenko)

   - Make the ACPI EC driver support compile-time conditional and allow
     ACPI to be built without CONFIG_HAS_IOPORT (Arnd Bergmann)

     Ian King)

   - Rearrange the processor_perflib code in the ACPI processor driver
     to avoid compiling x86-specific code on other architectures (Arnd
