Switch to the generic hdmi parser for codec id 1002:aa01 (ATI R6xx
HDMI), as the codec appears to work fine with it.
Note that the codec is still limited to stereo output only, despite it
reportedly being multichannel capable. Some as of yet unknown quirks
will be needed to get that working.
Testing was done on 2.6.36 by John Ettedgui.

Thanks, applied now.

Regarding the multi-channel LPCM: this is definitely a thing we need a
help from ATI/AMD... I'm going to try ping some known people.
(But don't expect too much :)

As per the "ALSA Multichannel through HDMI" thread, the generic parser
seems to work for this. So here's a patch against sound master.
