drm/i915/xelpd: Calculate VDSC RC parameters

Browse source

Add methods to calculate rc parameters for all bpps, against the fixed
arrays that we already have for 8,10,12 valid o/p bpps, to cover RGB 444
formats.  Our hw doesn't support YUV compression yet.  The calculations
used here are from VESA C model for DSC 1.1
