ASoC: soc-dai: add flag to mute and unmute stream during trigger
In some setups like Speaker amps which are very sensitive, ex: keeping them
unmute without actual data stream for very short duration results in a
static charge and results in pop and clicks. To minimize this, provide a way
to mute and unmute such codecs during trigger callbacks.
