drm/amd/display: Add minimal pipe split transition state
[WHY?]
When adding/removing a plane to some configurations, unsupported pipe
programming can occur when moving to a new plane. Such cases include pipe
split on multi-display, with MPO, and/or ODM.
[HOW?]
Add a safe transistion state that minimizes pipe usage before programming
new configuration. When adding a plane, the current state has the least
pipes required so it is applied without splitting. This must be applied
prior to updating the plane_state for seamless transition. When removing a
plane, the new state has the least pieps required so it is applied without
splitting.
