We may end up with no planes set yet, depending on the ordering, but we should have the proper blanking state which is either handled by either DPG or TG depending on the hardware generation. Check both to determine the proper blanked state.

I've grabbed 34b86b75dfc9 ("drm/amd/display: Use swap() where appropriate") as a dependency and queued both for 5.4.
Nevermind, looks like it also depends on functionality from eb7a74a36c24 ("drm/amd/display: Add DCN2 OPP").
