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.
