[DRIVER][TLV320] add missing dapm controls and routes

Add the "MAL Switch" and "MAR Switch" dapm controls to the LOL/LOR output
mixers, and setup their routing. This allows to connect the mixer amplifiers
to the Line Out outputs. Previously, the mixer amps could only be connected
to the headphone output.

Also add the "LOR Switch" control to LOL, to enable redirecting LOR output
to LOL (necessary to route differential mono input from IN1 to both LOL and
LOR).
