[PATCH v2 6/8] ASoC: soc-pcm: check DAI's activity more simply

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

DAI is counting its activity, and both playback/capture directional
activity. When considering mute, DAI's activity is enough instead of
caring both playback/capture.
This patch makes mute check simply.
