ASoC: Add TI tlv320aic32x4 codec support.
This patch adds support for tlv320aic3205 and tlv320aic3254 codecs. It doesn't include miniDSP support for aic3254. Signed-off-by: Javier Martin <javier.martin@vista-silicon.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
