[PATCH 18/37] drm/amd/display: Remove SubVp support if src/dst rect does not equal stream timing

[Rodrigo Siqueira]

From: Saaem Rizvi <SyedSaaem.Rizvi at amd.com>

Current implementation of SubVP does not support cases where stream
timing matched neither the destination rect nor the source rect.

Will need to further debug to see how we can support these cases.
