[PATCH 5.15 120/244] ASoC: tas2770: Drop conflicting set_bias_level power setting

From: Martin Povišer <povik+lin@cutebit.org>

commit 482c23fbc7e9bf5a7a74defd0735d5346215db58 upstream.

The driver is setting the PWR_CTRL field in both the set_bias_level
callback and on DAPM events of the DAC widget (and also in the
mute_stream method). Drop the set_bias_level callback altogether as the
power setting it does is in conflict with the other code paths.
