drm/amd/display: Add check for validating unsupported ODM plus MPO case
[Why]
We do not currently support ODM plus MPO on only one side of the
screen. This unsupported case causes validation calculations to
divide by zero due to invalid viewport values.
[How]
Add stopgap for the validation of ODM plus MPO on one side of
screen case.
