ASoC: tas2770: Fix handling of mute/unmute
Because the PWR_CTRL field is modeled as the power state of the DAC
widget, and at the same time it is used to implement mute/unmute, we
need some additional book-keeping to have the right end result no matter
the sequence of calls. Without this fix, one can mute an ongoing stream
by toggling a speaker pin control.
