[Intel-gfx] [PATCH 1/4] drm/i915/display: Add CDCLK actions to intel_cdclk_state

[Anusha Srivatsa <anusha.srivatsa@intel.com>]

This is a prep patch for what the rest of the series does.

Add existing actions that change cdclk - squash, crawl, modeset to
intel_cdclk_state so we have access to the cdclk values
that are in transition.
