Prepare for next patches (Improving BKDG implementation of P-states,
CPU and northbridge frequency and voltage handling for Fam 10 in SVI mode). No change of behaviour intended. Refactor FAM10 fidvid . prep_fid_change was already long and it'd get longer with forthcoming patches. We now take apart F3xDC[NbsynPtrAdj], Northbridge/core synchronization FIFO pointer adjust, to its own function.
