ASoC: kirkwood-dma: remove channel restrictions
This is part of a patch found in Rabeeh Khoury's git tree for the cubox. With SPDIF passthrough, we are not restricted to just two channels of audio; we can support however many channels the non-audio stream can itself support. In any case, kirkwood-dma is not involved in the format selection. So yet rid of this restriction.
