PNPACPI: cope with invalid device IDs

If primary ID (HID) is invalid try locating first valid ID on compatible
ID list before giving up.

This helps, for example, to recognize i8042 AUX port on Sony Vaio VPCZ1
which uses SNYSYN0003 as HID. Without the patch users are forced to
boot with i8042.nopnp to make use of their touchpads.
