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

Depends on a bunch of patches upstream doing bringup of Display (DSI),
DisplayPort, GPU, and then finally audio could land. But we're blocked
on DPU 1:1:1 topology for all of that unfortunately.

And also machine driver for sound just exists a bit hackily.

Thanks for sharing this, Luca. Can you please resubmit this once it's
ready to be merged, so that I don't need to keep track of it?

Regards,
Bjorn

Definitely, though I don't expect it to be soon unfortunately, maybe you
can ask your colleagues though to fix that DPU 1:1:1 topology ;)
