On Zork(picasso) platform we run verstage on the PSP. It has its own
timer, but the frequency is not matched with TSC.
To ease the work to merge timestamps from the PSP and TSC, add a layer
around tsc to have microsecond granularity for timestamp table. PSP
already records timestamp in microseconds.
BUG=b:159220781
BRANCH=zork
TEST=build, flash and boot, check timestamps are correct

Picasso's TimeStamp Counter is a new design and different than
Stoney Ridge. Although advertised as invariant, the ST TSC did
not become so until midway through POST making it an unreliable
source for measuring time. This is not the case for Picasso.
Remove the Stoney Ridge monotonic timer code and rely on the TSC.
Modify the calculation used in Family 15h of finding the number
of boost states first, and get the frequency directly out of the
Pstate0 register.

So that everyone can see what's being updated from stoney, we're
starting with a direct copy of the stoney directory. There are
arguments both for and against doing it this way, but I believe
This the most transparent way. We've moved much of the duplicated
stoney code into the soc/amd/common directory and will continue
that work as it becomes obvious that we have unchanged code between
the SOCs.
Makefile.inc has been renamed as makefile.inc so that it won't
build in jenkins until the directory is updated.
Other than that change, this is an exact copy of the stoneyridge
SOC directory which will be updated in the follow-on commits in
the patch train.
