The DisplayPort found on RK3576 is very similar to that of RK3588,
but work in qual pixel mode and support for MST.

This patch series aims to add basic display output, not include
audio and MST, which will be the work for the next stage.

Only test with 2 lane standard DP port output now.

This is a nice minimal series :) I got it working to some degree on
the RK3576 Sige5 USB-C port. The display connection detection is
_very_ unstable, but that part is handled by the TypeC Port Manager
and unrelated to the DP controller (and already an issue on the RK3588
based Rock 5B). IF the display is detected (i.e. USB-C side worked
properly), the DP controller managed to do proper output too. Thus
I believe this should be merged. I plan to look into the TCPM issues
in the meantime.
