[Intel-gfx] [PATCH v2 12/13] drm/i915: Consolidate more cdclk state handling

[Ville Syrjala]

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

Move the initial setup of state->min_cdclk[]/min_voltage_level[]
into intel_modeset_calc_cdclk() alongside the rest of the global
cdclk state. And the counterparts we move into
intel_cdclk_swap_state().
