Merge branches 'acpi-resource', 'acpi-pmic', 'acpi-battery' and 'acpi-apei'

Merge ACPI resources handling changes, ACPI PMIC and battery drivers
changes and ACPI APEI changes for 6.3-rc1:

 - Add two more entries to the ACPI IRQ override quirk list (Adam
   Niederer, Werner Sembach).

 - Add a pmic_i2c_address entry for Intel Bay Trail Crystal Cove to
   allow intel_soc_pmic_exec_mipi_pmic_seq_element() to be used with
   the Bay Trail Crystal Cove PMIC OpRegion driver (Hans de Goede).

 - Add comments with DSDT power OpRegion field names to the ACPI PMIC
   driver (Hans de Goede).

 - Fix string termination handling in the ACPI battery driver (Armin
   Wolf).

 - Limit error type to 32-bit width in the ACPI APEI error injection
   code (Shuai Xue).

* acpi-resource:
  ACPI: resource: Do IRQ override on all TongFang GMxRGxx
  ACPI: resource: Add IRQ overrides for MAINGEAR Vector Pro 2 models

* acpi-pmic:
  ACPI: PMIC: Add comments with DSDT power opregion field names
  ACPI: PMIC: Add pmic_i2c_address to BYT Crystal Cove support

* acpi-battery:
  ACPI: battery: Increase maximum string length
  ACPI: battery: Fix buffer overread if not NUL-terminated
  ACPI: battery: Fix missing NUL-termination with large strings

* acpi-apei:
  ACPI: APEI: EINJ: Limit error type to 32-bit width
