Subject: [PATCH V4 03/11] ACPI: remove ids that does not comply with the ACPI PNP id rule

The acpi pnp scan handler id list just copies all the ids from all the
struct pnp_device_id instances, but some of them do not
comply with the ACPI PNP id rule (3 Alpha Charactors + 4 Hex numbers).

For those ids, the coressponding devices will never be enumerated
via ACPI, so it is safe to remove those ids from the PNPACPI white list.
