Merge branches 'acpi-scan', 'acpi-drivers', 'acpi-pm' and 'acpi-resources'

* acpi-scan:
  ACPI: bus: Introduce acpi_dev_get() and reuse it in ACPI code
  ACPI: scan: Utilize match_string() API
  ACPI: scan: Call acpi_get_object_info() from acpi_set_pnp_ids()
  ACPI: scan: Drop sta argument from acpi_init_device_object()
  ACPI: scan: Drop sta argument from acpi_add_single_object()
  ACPI: scan: Rearrange checks in acpi_bus_check_add()
  ACPI: scan: Fold acpi_bus_type_and_status() into its caller

* acpi-drivers:
  ACPI: HED: Drop unused ACPI_MODULE_NAME() definition

* acpi-pm:
  ACPI: power: Turn off unused power resources unconditionally
  ACPI: scan: Turn off unused power resources during initialization

* acpi-resources:
  resource: Prevent irqresource_disabled() from erasing flags
