From: Kuninori Morimoto <[email protected]>
Asymmetric audio interface formats exist in ak4613 by same
register settings.
Capture Playback
24bit LEFT_J 16bit RIGHT_J
24bit LEFT_J 20bit RIGHT_J
24bit LEFT_J 24bit RIGHT_J
24bit LEFT_J 24bit LEFT_J
24bit I2S 24bit I2S
These asymmetric formats makes driver / behavior difficult.
It is not HW limitation, but SW limitation. To makes code reading
easy, this patch doesn't remove code, but just comment out.
