ASoC: tas5720: set bit 7 in ANALOG_CTRL_REG for TAS5720A-Q1 during probe
Set the reserved bit 7 in the ANALOG_CTRL_REG for the TAS5720A-Q1 device,
when probing.
The datasheet mentions that the bit should be 1 during reset/powerup.
The device did not initialize before setting this value to 1. So, this
could be a quirk of this device. Or it could be a quirk with the board on
which it was tested.
That is why this patch is separate from the patch that adds support for the
TAS5720A-Q1 device.
