    drm/i915: Call intel_pre_plane_updates() also for pipes getting enabled
    
    [ Upstream commit d21a3962d3042e6f56ad324cf18bdd64a1e6ecfa ]
    
    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.
