[Intel-gfx] [PATCH 04/17] drm/i915: Move more cdclk state handling into the cdclk code

[Ville Syrjala]

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

Move the initial setup of state->{cdclk,min_cdclk[],min_voltage_level[]}
into intel_modeset_calc_cdclk(), and we'll move the counterparts into
intel_cdclk_swap_state(). This encapsulates the cdclk state much better.
