ASoC: mxs: Setup dma data in DAI probe
This allows us to access the DAI DMA data when we create the PCM. We'll use this when converting mxs to generic DMA engine PCM driver. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Tested-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
