[Intel-gfx] [PATCH 13/14] drm/i915: Replace the .modeset_commit_cdclk() hook with a more direct .set_cdclk() hook

[ville.syrjala at linux.intel.com]

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

With the cdclk state, all the .modeset_commit_cdclk() hooks are
now pointless wrappers. Get rid of the extra indirection and just
use set_cdclk function directly.
