ASoC: samsung: i2s: Configure dmaengine playback/capture DAI DMA data

This patch configures the standard alsa dmaengine configure dai data.
The dma address, width and maxburst size will be initialized during
cpu dai probe process, in which the address width is assigned with
a default value as four bytes. Then when the hardware parameters are
configured as playback or capture are started, the dma address width
will be configured again according to current sound channels.

After the configuration, this patch will set the dai dma data into
the private dma data field in snd_soc_dai structure.
