Martin Povišer 6bc81c1b63 ASoC: tas2764: Fix mute/unmute
[ Upstream commit f5ad67f13623548e5aff847f89700c178aaf2a98 ]

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 permanently mutes an
ongoing stream by toggling the associated speaker pin control.

(This mirrors commit 1e5907bcb3a3 ("ASoC: tas2770: Fix handling of
mute/unmute") which was a fix to the tas2770 driver.)
