topology: tgl-max98373-rt5682: adjust channel usage for sdw DSM support

For original design, there are 4 channels 24bit stream for playback
and 8 channels 24bit IV feedback for capture stream. This requirement
exhausts all resource on single link. Now adjust it to a 2 channels stream
for playback and a 4 channels stream for capture
