Merge branch 'acpi-enumeration'

* acpi-enumeration:
  ACPI / scan: use platform bus type by default for _HID enumeration
  ACPI / scan: always register ACPI LPSS scan handler
  ACPI / scan: always register memory hotplug scan handler
  ACPI / scan: always register container scan handler
  ACPI / scan: Change the meaning of missing .attach() in scan handlers
  ACPI / scan: introduce platform_id device PNP type flag
  ACPI / scan: drop unsupported serial IDs from PNP ACPI scan handler ID list
  ACPI / scan: drop IDs that do not comply with the ACPI PNP ID rule
  ACPI / PNP: use device ID list for PNPACPI device enumeration
  ACPI / scan: .match() callback for ACPI scan handlers
