Merge branches 'acpi-battery', 'acpi-ec', 'acpi-pfr' and 'acpi-osl'

Browse Source 
Merge updates of the ACPI battery and EC drivers, an ACPI Platform
Firmware Runtime (PFR) telemetry driver update and an ACPI OS support
layer change for 6.13-rc1:

 - 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).

* acpi-battery:
  ACPI: battery: Check for error code from devm_mutex_init() call
  ACPI: battery: use DEFINE_SIMPLE_DEV_PM_OPS
  ACPI: battery: initialize mutexes through devm_ APIs
  ACPI: battery: allocate driver data through devm_ APIs
  ACPI: battery: check result of register_pm_notifier()

* acpi-ec:
  ACPI: EC: make EC support compile-time conditional

* acpi-pfr:
  ACPI: pfr_telemetry: remove redundant error check on ret

* acpi-osl:
  ACPI: allow building without CONFIG_HAS_IOPORT
