This UCM config is copied from https://gitlab.com/pine64-org/pine64-alsa-ucm/, which is BSD-3-Clause licensed.

This UCM has been tested via Pulseaudio's ALSA_CONFIG_UCM2 environment variable, but I've not yet tested that this UCM, when included in this package, is correctly recognised on a PinePhone as part of this

Todo:

* [ ] Test that this UCM is correctly recognised on a PinePhone.
