Subject: [PATCH] sof-soundwire: rt1320: add playback control switch

This patch defines 'rt1320 OT23' as PlaybackMixerElem and
a remapped one 'rt1320 OT23 Playback Switch' when using one
or two amps.

And also attach rt1320 OT23 controls to speaker LED.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/743
