Add the required nodes for sound playback via a connected external display (DisplayPort over USB-C).

In user space just the following route needs to be set (e.g. using ALSA UCM):

amixer -c0 cset name='DISPLAY_PORT_RX Audio Mixer MultiMedia1' 1

Afterwards one can play audio on the MultiMedia1 sound device, e.g.:

aplay -D plughw:0,0 test.wav
