Improving BKDG implementation of P-states,
CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Bring F3xD4 (Clock/Power Control Register 0) more in line
with BKDG i more cases. It requires looking at the CPU package type
so I add a function for that (in the wrong place?) and some
new constants
