Ville Syrjälä 93d67b62c7 drm/i915: Call intel_pre_plane_updates() also for pipes getting enabled
[ Upstream commit d21a3962d3 ]

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.
