ALSA: hda: Add STAC92HD83XXX_PWR_REF quirk 



Some revisions of the 92hd8xxx codec's not supporting port power
downs in which the using of it causes capture and also randomly
playback streams to not function at all. Thus by disabling it by
default and adding a option to enable it manually will fix all issue
on current and future revisions.
