This patch is also required to clean up a connector leak in i915 driver unload as well, and also to clean up plane state destruction there. Nouveau needs it to unpin some framebuffers during suspend, but even if none of this was true, this is the right way to handle disable_all.

Looking at DPMS is fragile.
