ASoC: tegra: Restore AC97 support

Browse source 
commit de8fc2b0a3 upstream.

The device-tree of AC97 codecs need to be parsed differently from I2S
codecs, plus codec device may need to be created. This was missed by the
patch that unified machine drivers into a single driver, fix it. It should
restore audio on Toradex Colibri board.
