sound_card_init: Remove workaround for applying TAS2563 Calibration Data

The data length portion for TAS2563 Calibration Data is now not
automatically changed. Remove the workaround where we add a buffer byte
and just apply the data length byte to the calibration data instead.

BUG=b:345629513
TEST=`amixer -c 0 contents` and check that the Speaker Calibrated Data
is applied correctly
