Patches 13, 14 and this 15 look ok to me. Those num/den combos in 13 I
cannot bet my head on but the plumbing look all ok.
Also if on 1..8 some patch wasn't pushed yet, those are all

Now that the planes declare their minimum cdclk requirements properly
we don't need to check the cdclk in skl_max_scale() anymore. Just check
against the maximum downscale ratio, and move the code next to it's
only caller.
