[PATCH] oss: AC97 quirk facility

Add a quirk facility for AC97 in OSS, and add a quirk list for the
i810_audio driver.

This allows automatically "correct" behaviour for sound hardware w/ known
oddities.  For example, many cards have the headphone and line-out outputs
swapped or headphone outputs only.

The code is stolen shamelessly from ALSA, FWIW...
