soc/intel/skylake/vr_config: Add loadline defaults
In addition to zero IccMax specified by mainboard with socketed CPU, allow
a zero LoadLine default.
The SoC code will fill in the default AC/DC LoadLine values are per
datasheets:
* "7th Generation Intel® Processor Families for H Platforms, Vol 1"
Document Number: 335190-003
* "7th Generation Intel® Processor Families for S Platforms and
Intel ®Core™ X-Series Processor Family, Vol 1"
Document Number: 335195-003
The AC/DC LoadLine is CPU and board specific.
TODO: Find out how to get the LoadLine from vendor firmware and find out
how to map those to different CPU LoadLines.
