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 F3x[84:80],
ACPI Power State Control Registers, to its own function.
