Note that exynos_crtc->enabled doesn't match drm_crtc->enabled perfectly
since the exynos one reflect hw state (including dpms). You want to look
at crtc->state->active instead on functions enabling stuff, and
old_crtc_state->active on functions disabling stuff (we don't wire that
through everywhere yet).
