Bug description:
  SRU Justification

  [Impact]

  Found Kernel error 'OF: graph: no port node found in
  /axi/display@fd4a0000'.

  ubuntu@kria:~$ sudo dmesg --level err
  ...
  [    6.575032] OF: graph: no port node found in /axi/display@fd4a0000  
<--------- Here
  ...

  [Fix]

  * Backport 1f367ee9554af5d6 from mainline
  The DPSUB DT bindings now specify ports to model the connections with
  the programmable logic and the DisplayPort output. Add them to the
  device tree.

  [Test Plan]

  * Checked error message is gone after applying the patch.

  [Where problems could occur]

  * DT update, low potential for regression.
