intel/skylake: Fix bug in VR configuration with FSP 2.0
With the move to FSP 2.0 the number of VR types supported was
reduced to 4, and the VR_RING type is no longer present.
This means all existing boards using FSP 2.0 are incorrectly
passing VR configuration into FSP as the values corresponding to
"GT Sliced" and "GT Unsliced" have changed.
Fix this by updating the skylake SOC VR handling to account for
changes in the FSP configuration and no longer provide VR_RING
type when using FSP 2.0.
