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.

Two extra notes:
I don't quite understand whether the sound driver should have SoC-specific compatible or device-specific compatible. Some earlier patches by another author for a QCM6490 board and a QCS6490 board use device-specific compatible - but from what I can tell this is not how it's generally done for other sound drivers?
Unfortunately DisplayPort enablement itself for Fairphone 5 is not upstream yet. This is blocked by DSI display bringup upstream which is blocked by DSC 1:1:1 not being supported upstream yet and just working with a hacky patch. Nevertheless, DisplayPort audio was validated working with no additional sound-related changes so once DisplayPort gets enabled, sound should also just work upstream.
You can enable DP and keep DSI disabled for the time being
I need to enable dispcc for DP which breaks simple-fb from my testing?
Maybe I can figure out the correct clocks and power domains to put into the simple-fb node? Do you think that would work and be sufficient to make both simple-fb and DP work?
