arm64: dts: qcom: qcm6490-fairphone-fp5: Add DisplayPort sound support

Browse source

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
