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 = ".
