Together with the static helper functions drm_crtc_prepare_encoders and drm_encoder_disable (which will be simplified in the next patch, but for now are 1:1 copies). Again, no changes beside new names for these functions. Also call our new set_mode instead of the crtc helper one now in all the places we've done so far. v2: Call the function just intel_set_mode to better differentia it from intel_crtc_mode_set which really only does the ->mode_set step of the entire modeset sequence on one crtc. Whereas this function does the global change.
