ACPI / scan: introduce platform_id device PNP type flag
Only certain types of ACPI device objects can be enumerated as platform devices, so in order to distinguish them from the others introduce a new ACPI device PNP type flag, platform_id, and set it for devices with a valid _HID to start with. This change is based on a Zhang Rui's prototype. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com>
