/**
* Family 10h core 0 entry point for performing the "Northbridge COF and
* VID Configuration" algorithm.
*
* The steps are as follows:
* 1. Determine if the algorithm is necessary by checking if all NB FIDs
* match in the coherent fabric. If so, check to see if NbCofVidUpdate
* is zero for all CPUs. If that is also true, no further steps are
* necessary. If not + cold reset, proceed to step 2. If not + warm
* reset, proceed to step 8.
* 2. Determine NewNbVid & NewNbFid.
* 3. Copy Startup Pstate settings to P0/P1 MSRs on all local cores.
* 4. Copy NewNbVid to P0 NbVid on all local cores.
* 5. Transition to P1 on all local cores.
* 6. Transition to P0 on local core 0 only.
* 7. Copy NewNbFid to F3xD4[NbFid], set NbFidEn, and issue a warm reset.
* 8. Update all enabled Pstate MSRs' NbVids according to NbVidUpdateAll
* on all local cores.
* 9. Transition to Startup Pstate on all local cores.
*
* @param[in] FamilySpecificServices The current Family Specific Services.
* @param[in] CpuEarlyParamsPtr Service related parameters (unused).
* @param[in] StdHeader Config handle for library and services.
