drm/i915: Make .modeset_calc_cdclk() mandatory
While not all platforms allow us to change the cdclk frequency
we should still verify that the fixed cdclk frequency isn't
too low. To that end let's cook up a .modeset_calc_cdclk()
implementation that only does the min_cdclk vs. actual cdclk
frequency check for such platforms.
Also we mustn't forget about double wide pipe on gen2/3 when
doing this.
