CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Add to init_fidvid_stage2 some step
mentioned in BKDG 2.4.2.7 that was missing . Some lines
are dead code now, but may handy if one day we support
revison E CPUs.

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.

Factor out some common expressions.
Add an error message when coreboots hangs waiting for a pstate
that never comes (it happened to me), and throw some
paranoia at it for good mesure.
If I understood BKDG fam10 CPUs never need a software initiated vid transition,
because the hardware knows what to do when you just request
a Pstate change if the cpu is properly configured. In fact
unifying a little what PVI and SVI do was better for my board (SVI).
So I drop transitionVid, which I didn't understand either (why
did it have a case for PVI if it is never called for PVI ?
Why did the PVI case distinguigh cpu or nb when PVI is
theoretically single voltage plane ? ).

Contemplate the possibility of nbCofVidUpdate not being
defined, trying to get closer to BKDG

BKDG says nbSynPtrAdj may also be 6 sometimes.

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.

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

Supports single and split plane systems. Set P0 on all cores for best performance.
All APs will be in hlt(C1).
The platform warm rest logic has been updated to alway reset for HT and FID/VID setup. It is not optional anymore.

This fixes many default setting as well as erratas.
Some CPU core functions were moved from the HT init and platform specific code to the generic Fam10 CPU code.
