commit de8fc2b0a3f9930f3cbe801d40758bb1d80b0ad8 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.
