Now that the dpll updates are (mostly) atomic, the .off() code is no longer
used,
and there are no more callers for intel_put_shared_dpll. Move all the updates
done in intel_crtc_disable to intel_modeset_update_state, one less special case
to worry about.
Changes since v1:
- Move drm_atomic_helper_swap_state up.
