ASoC: soc-dai: move snd_soc_dai_stream_valid() to soc-dai.c
snd_soc_dai_stream_valid() is function to check stream validity.
But, some code is using it, some code are checking stream->channels_min
directly. Doing samethings by different method is confusable.
This patch uses same funcntion for same purpose.
