Merge branches 'acpi-ec', 'acpi-fan', 'acpi-video' and 'acpi-misc' 

* acpi-ec:
  ACPI / EC: Deny write access unless requested by module param

* acpi-fan:
  ACPI / fan: Make struct dev_pm_ops const

* acpi-video:
  ACPI / video: remove unused device_decode array

* acpi-misc:
  ACPI / util: remove redundant check if element is NULL
  ACPI: Add acpi_force_32bit_fadt_addr option to force 32 bit FADT addresses
  drivers/acpi: make pmic/intel_pmic_crc.c explicitly non-modular
  drivers/acpi: make apei/ghes.c more explicitly non-modular
  drivers/acpi: make bgrt driver explicitly non-modular

acpi_force_32bit_fadt_addr
force FADT to use 32 bit addresses rather than the
64 bit X_* addresses. Some firmware have broken 64
bit addresses for force ACPI ignore these and use
the older legacy 32 bit addresses.
acpica_no_return_repair [HW, ACPI]
Disable AML predefined validation mechanism
