ASoc: tas2781: Enable RCA-based playback without DSP firmware download
[ Upstream commit 9f774c757e3fb2ac32dc4377e8f21f3364a8df81 ]
In only loading RCA (Reconfigurable Architecture) binary case, no DSP
program will be working inside tas2563/tas2781, that is dsp-bypass mode,
do not support speaker protection, or audio acoustic algorithms in this
mode.
