Merge branches 'acpi-x86', 'acpi-soc', 'acpi-pmic' and 'acpi-apple'

* acpi-x86:
  ACPI / boot: Add number of legacy IRQs to debug output
  ACPI / boot: Correct address space of __acpi_map_table()
  ACPI / boot: Don't define unused variables

* acpi-soc:
  ACPI / LPSS: Don't abort ACPI scan on missing mem resource

* acpi-pmic:
  ACPI / PMIC: xpower: Do pinswitch magic when reading GPADC

* acpi-apple:
  spi: Use Apple device properties in absence of ACPI resources
  ACPI / scan: Recognize Apple SPI and I2C slaves
  ACPI / property: Support Apple _DSM properties
  ACPI / property: Don't evaluate objects for devices w/o handle
  treewide: Consolidate Apple DMI checks
