drm/amd/display: Use full update for swizzle mode change

Browse Source 
[WHY & HOW]
1) We did linear/non linear transition properly long ago
2) We used that path to handle SystemDisplayEnable
3) We fixed a SystemDisplayEnable inability to fallback to passive by
   impacting the transition flow generically
4) AFMF later relied on the generic transition behavior

Separating the two flows to make (3) non-generic is the best immediate
coarse of action.

DC can discern SSAMPO3 very easily from SDE.
