drm/amd/display: DispalyPort: Write OUI only if panel supports it
[why]
Organizational Unit Identifier register is optional, and its
presence is published via Down Stream Port Count register.
Writing this register when not available will result in errors
[how]
Read this register and continue writing OUI only if the panel
has the support advertised.
