sof-soundwire: rt1308: Fix single amp configuration

alsa-project/alsa-ucm-conf pull request #402 was opened from ujfalusi:

If the device have single rt1308 amp then the codec's Channel Select should be set to "LR" and not to "LL". "LL" is only valid if we have 2 amps, in that case one is the Left and the other is the Right channel.

This fixes for example Dell Latitude 9520 which only played on the Left speaker, Right is silent.
