Improving BKDG implementation of P-states,
CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
I didn't understand quite why it did that iwth F3xA0 (Power
Control Misc Register) so I moved Pll Lock time to rules in defaults.h
and reimplemented F3xA0 programming. A later patch will remove
a part I don't know what's mean to do.
