Add CVB tables with different chip characterization, so that we can
generate the customize OPP table that suitable for different chips with
different SKUs.
The parameter 'tune_high_min_millivolts' is first time introduced in
this patch, which didn't use in the DFLL driver for clock and voltage
tuning before. It will be used later when DFLL in high voltage range.
