ACPI: Set fake hid for non-PNPID ACPI devices
We do this mainly because:
1. hid is used to match ACPI devices and drivers.
.match method which is incompatible to driver model
can be deleted from acpi_driver.ops then.
2. As the .uevent method mark ACPI drivers by PNPID,
fake hid is set to non-PNPID devices so that udev script
can load the right ACPI driver by looking for
"HWID = " or "COMPTID = ".
