drm/i915: Compute per-crtc min_cdclk earlier
Currently we compute the min_cdclk for each pipe during
intel_cdclk_atomic_check(). But that is too late for the
pipe prefill vs. vblank length checks (done during
intel_compute_global_watermarks).
We can't just reorder these things due to other dependencies,
so instead pull only the per-crtc minimum cdclk calculation
ahead. We should have enough information for that as soon
as we've computed the min cdclk for the planes.
