Add PinePhone UCM
This is tested with, ALSA version 1.2.4 and pulseaudio 14.0
This also licenses them to BSD-3-Clause license which is what is used by alsa-ucm-conf upstream to eventually move it there.
This UCM are copied from the postmarketOS pmaports as ultimately most distributions have forked configs from them and this is currently most up-to-date source.
