[Intel-gfx] [PATCH 3/3] drm/atomic: refuse changing CRTC for planes while active

Very strictly speaking this is possible if you have special hw and genlocked CRTCs. In general switching a plane between two active CRTC just won't work so well and is probably not tested at all. Just forbid it. The exception is when both CRTC do a full modeset, then it should be no problem at all
