drm/amd/display: Check validation passed after applying pipe split changes

Browse Source 
[WHY?]
Validation can fail for configurations that were previously supported, by only
changing parameters such as the DET allocations, which is currently unexpected.

[HOW?]
Add a check that validation passes after applying pipe split related changes.
