Subject: [PATCH] sof-soundwire: rt1320: add rt1320 dmic config

This patch adds configs for rt1320 dmic function.
It defines the MicMixerElem, a remapped control for the two rt1320-dmic
case, and also attaches rt1320 FU capture controls to the mic LED.

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