Merge branches 'acpi-numa', 'acpi-sysfs', 'acpi-pmic', 'acpi-soc' and 'acpi-ged' 

* acpi-numa:
  ACPI / NUMA: ia64: Parse all entries of SRAT memory affinity table

* acpi-sysfs:
  ACPI: sysfs: Make ACPI GPE mask kernel parameter cover all GPEs

* acpi-pmic:
  ACPI / PMIC: Convert to use builtin_platform_driver() macro
  ACPI / PMIC: constify platform_device_id

* acpi-soc:
  ACPI / LPSS: Do not instiate platform_dev for devs without MMIO resources
  ACPI / LPSS: Add device link for CHT SD card dependency on I2C

* acpi-ged:
  ACPI: GED: unregister interrupts during shutdown
