ASoC: soc-dai.h: add snd_soc_dai_dma_data_set/get() for low level

Current ASoC has snd_soc_dai_set/get_dma_data() which is assuming
struct snd_pcm_substream to get Playback/Capture direction.

But, many drivers want to use it not through snd_pcm_substream.
This patch adds more low level snd_soc_dai_dma_data_set/get() for it,
and previous functions will be macro for it.
