ASoC: sh: fsi: modify selection method of I2S/PCM/SPDIF format
Current format selection of FSI-codecs depended on platform information for FSI, and chip default settings for codecs. It is not understandable/formal method. This patch modify FSI and FSI-codecs to use snd_soc_dai_set_fmt. But FSI can use I2S/PCM and SPDIF format today. It can be selected to I2S/PCM by snd_soc_dai_set_fmt, but can not select SPDIF. So, this patch change FSI platform information to have DAI/SPDIF mode. If platform selects DAI mode (default), FSI-codecs can select I2S/PCM by snd_soc_dai_set_fmt, and if it is SPDIF mode, FSI become SPDIF format.
