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)

   - 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)"
