ASoC: add soc-dai.c
Current ALSA SoC has many snd_soc_dai_xxx() function which is using dai->driver->ops->xxx. But, some of them are implemented as snd_soc_dai_xxx(), but others are directly using dai->driver->ops->xxx. Because of it, the code is not easy to read. This patch creats new soc-dai.c and moves snd_soc_dai_xxx() functions into it. One exception is snd_soc_dai_is_dummy() which is based on soc-utils local variable. We need to keep it as-is there. Others which is directly using dai->driver->ops->xxx will be implemented at soc-dai.c by incremental patches.
