ALSA: hda - Set default GPIO for STAC/IDT codecs

IDT92HD73xx and STAC927x codecs use GPIO0 bit as EAPD on many machines.
However, currently we don't set it unless the model is specified just
for safety reason.  But, most machines do need this bit, so this safety
handling is rather annoying.

This patch enables GPIO0 setup as default for them.  Many HP / Dell
laptops should work even without model override with this change.
