drm/i915/icl: use ranges for voltage level lookup

Browse source

Spec shows voltage level 0 as 307.2, 312, or lower and suggests to use
range checks. Prepare for having other frequencies in these ranges by
not comparing the exact frequency.

v2: invert checks by comparing biggest cdclk first (suggested by Ville)
