RB3Gen2 is capable of producing DisplayPort output on a dedicated
mini-DP connector and USB Type-C.
Utilize Abel's work for DP vs eDP selection to allow configuring both
controllers in DP-mode, then enable the two output paths.
Tested by driving fbcon to 4k@60 + 4k@30 concurrently.
Depends on 20240324-x1e80100-display-refactor-connector-v4-0-e0ebaea66a78@linaro.org

Changes in v2:
- Rebased on Abel's updated implementation
- Dropped DP driver changes, as Abel's new DP/eDP selection mechanism
obsoleted these.
- Squashed the two separate patches adding pmic-glink
- Corrected remoteproc firmware-name paths
- Described the mini-DP connector in DT, and hence no longer use the
internal HPD handler in DP driver
