Initial commit of auixp(4) driver. It's a driver for the audio part of ATI
IXP-200 and family motherboard chips. Its functional for both recording and playback. Note that quadraphonic and Dolby 5.1 audio are not tested by me but ought to work fine. I can set the number of channels etc. OK but i can't listen to the result. Any feedback on this performance would be greatly apreciated.
