drm/amd/display: prefer preferred link cap over verified link settings
[why]
when preferred link cap is set, we should always use
preferred in all validation.
we should not use preferred for some validation but use
verified for others.
[how]
create getter function that gets verified link cap.
if preferred is set, return preferred link settings instead.
