On Tegra the convention is to have a single machine driver that's controlling the whole audio subsystem. This was introduced after the AC97 driver was merged and ever since AC97 has been broken.
Move the clock handling to the machine driver, to be in line with the other Tegra drivers and give the machine driver full control over the single Tegra audio PLL.
On a Colibri T20, the AC97 Codec WM9712 gets detected and I can play audio after unmuting the right output: amixer -c 0 set 'Left HP Mixer PCM' on amixer -c 0 set 'Right HP Mixer PCM' on

Lucas, did you tried once to capture input? In my test using arecord -f cd, recorded sound is very slow (rate problem?)
