drm/radeon: properly handle crtc powergating commit 6c0ae2ab85fc4a95cae82047a7db1f688a7737ab upstream. Need to make sure the crtc is gated on before modesetting. Explicitly gate the crtc on in prepare() and set a flag so that the dpms functions don't gate it off during mode set. Noticed by sylware on IRC.
