[alsa-devel] [PATCH 2/2] ASoC: Intel: Split hsw_pcm_data for playback and capture

There may be 2 pcm streams for a same DAI at most, and these 2
streams should have different hsw_pcm_data, e.g. they have
different persistent data, so here we need split hsw_pcm_data
for playback and capture, to make sure they won't be mixed
and keep cleaned.
