[PATCH 01/31][SRU][OEM-5.6] drm/i915: Move more cdclk state handling into the cdclk code

[You-Sheng Yang]

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

BugLink: https://bugs.launchpad.net/bugs/1891451

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.
