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
