drm/i915/cdclk: Do intel_cdclk_update_crtc_min_cdclk() per-pipe

Browse Source 
Currently we call intel_cdclk_update_crtc_min_cdclk() per-plane.
That is rather wasteful, and also won't account for any of the
other per-pipe min_cdclk restrictions from
intel_crtc_compute_min_cdclk(). Change the behaviour to do
do the comparison per-crtc instead, and use the final min cdclk
as computed by intel_crtc_compute_min_cdclk().
