Add the necessary sound card bits and some dts additions to enable sound
over DisplayPort-over-USB-C, e.g. to a connected TV or monitor.

The UCM files can be found here:
https://gitlab.postmarketos.org/postmarketOS/pmaports/-/tree/master/device/testing/device-fairphone-fp5/ucm

This series - in spirit - depends on the series enabling DisplayPort in
the first place, but can land pretty independently, especially the ASoC
bits:

Changes in v2:
- Revamp series based on comments on v1, doesn't have much too much in
  common anymore

  changes from sc8280xp.c to sm8250.c
- This also changes the sound card compatible to from
  qcom,qcm6490-sndcard to fairphone,fp5-sndcard
