ALSA: asoc: core - merge structs snd_soc_codec_dai and snd_soc_cpu_dai.

This patch series merges struct snd_soc_codec_dai and struct
snd_soc_cpu_dai into struct snd_soc_dai in preparation for further
ASoC v2 patches.

This merger removes duplication in both DAI structures and simplifies
the API for other users.
