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.
