ASoC: mediatek: mt6359: update route for lineout mux
Originally, lineout playback source can only be DAC_3RD. Some SoC
masters only support stereo MTKAIF outputs, so lineout path can't be
used in such case.
MTKAIF connections are as follows.
MOSI0 -> DAC_L
MOSI1 -> DAC_R
MOSI2 -> DAC_3rd
In the patch, lineout playback source can be chosen between DAC_L and
DAC_3rd, so sound can be outputted via lineout even though SoC only
supports stereo MTKAIF outputs.
