[PATCH 5.19 312/717] ASoC: tas2764: Drop conflicting set_bias_level power setting

[Greg Kroah-Hartman]

From: Martin Povišer <povik+lin@xxxxxxxxxxx>

[ Upstream commit 09273f38832406db19a8907a934687cc10660a6b ]

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.

(This mirrors commit c8a6ae3fe1c8 ("ASoC: tas2770: Drop conflicting
set_bias_level power setting") which was a fix to the tas2770 driver.)

Fixes: 827ed8a0fa50 ("ASoC: tas2764: Add the driver for the TAS2764")
