Subject: drm/amd/display: Allow planes on all crtcs
Git-commit: 7df498fa4c241610ee22cfcfa648628d2ef908fd
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

4.9 kernel will always add the assigned crtc to possible_crtcs on a
plane. This is no longer the case on newer kernels. Make sure we allow
any plane on any crtc.
