[PATCH 11/11] drm/i915/cdclk: Unify cdclk max() parameter order

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

In some places we do
 min_cdclk = max(min_cdclk, other_min_cdclk)
and in other places we have the arguments swapped as
 min_cdclk = max(other_min_cdclk, min_cdclk)

Unify everyone to use the first order of arguments, because
it looks cleaner, especially within intel_crtc_compute_min_cdclk()
which is doing a lot of these back-to-back.
