drm/amd/display: fix incorrect odm change detection logic
[why]
The current ODM change detection only compares first two ODM slices.
If there are 4 ODM slices and the change is within the last two slices, the
logic fails to detect ODM change and cause us to skip ODM programming
unexpectedly.
[how]
Add a is ODM topology changed resource interface to check any ODM
topology changes with a more generic method.
