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/t...
This series - in spirit - depends on the series enabling DisplayPort in the first place, but can land pretty independently, especially the ASoC bits: https://lore.kernel.org/linux-arm-msm/20250312-fp5-pmic-glink-dp-v2-0-a55927...
The ASoC bits depend on the patches for USB audio offloading merged through Greg's tree so this cannot easily be applied for v6.16 through the sound tree. Either it waits for v6.17 or also goes through Greg's tree.

Changes in v2: - Revamp series based on comments on v1, doesn't have much too much in common anymore - Use sm8250 instead of sc8280xp sndcard file, so port other required changes from sc8280xp.c to sm8250.c - This also changes the sound card compatible to from qcom,qcm6490-sndcard to fairphone,fp5-sndcard - Link to v1: https://lore.kernel.org/r/20240809-fp5-dp-sound-v1-0-d7ba2c24f6b9@fairphone....
