intel/skylake: provide default VR configuration
FSP 1.8.0 will do nothing with the VR settings if VrConfigEnable is
non-zero. That behavior is not desired because it's not clear what
the behavior will be for various processor SKUs. Instead provide
default values for the VR config. Note that PSI3 and PSI4 are not
enabled for those defaults.
BUG=chrome-os-partner:48466
