[ALSA] hda-codec - Fix Gateway laptops with STAC9200 

Fix the output of Gateway laptops with STAC9200 codec chip.
They require the EAPD control for some pins.  These pins shouldn't be
powered down.
To enable EAPD control, a new model 'gateway' was added to STAC9200.
The known PCI SSIDs are included in the quirk list.
The fix was originally suggested by Brian Hinz, in ALSA bug#2948.
