USB-Audio: Add support for MOTU Ultralite mk5

alsa-project/alsa-ucm-conf pull request #422 was opened from clement-dufour:

Adds support for the [MOTU Ultralite mk5](https://motu.com/en-us/products/gen5/ultralite-mk5/) soundcard. I named each device after their names on the MOTU Cuemix Control application.

Successfully tested on my hardware, see the [alsa-info.sh output](http://alsa-project.org/db/?f=ca07253279e53fa354820f356f6beb5d2026d23f).
