soc/intel/cannonlake: Add VR config for CFL, CNL and WHL
Add VR config IccMax, DC and AC loadline defaults and voltage regulator maximum for all CFL, CNL and WHL. This supports mainboards with replaceable CPUs and provides sane defaults for boards that are missing the devicetree overwrite. Remove the default IccMax to make use of the introduced lookup-table. Also change some hex values to decimal. I couldn't find CML datasheet, so those are left out for now. Used Doc #337344 and #338023 Section 7.
