From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
We used to call intel_pre_plane_updates() for any pipe going through
a modeset whether the pipe was previously enabled or not. This in
fact needed to apply all the necessary clock gating workarounds/etc.
Restore the correct behaviour.
Fixes: 39919997322f ("drm/i915: Disable all planes before modesetting any pipes")
