Improving BKDG implementation of P-states,
CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Looking at BKDG the process for updating
Pstate Nb vid after warn reset seemed
more similar to the codethat was there fo
pvi than the one for svi, so I called the
pvi function passing a pvi/svi flag. I don't
find documentation on why should UpdateSinglePlaneNbVid()
be called in PVI, but since I can't test it,
I leave it as it was.
This patch showed some progress beyond fidvid in my
boar,d but only sometimes, most times it just didn't
work.
