amd/stoneyridge: Add warm reset detection
Extend the existing reset handling features in Stoney Ridge to plan for,
and recognize, warm resets. The ColdRstDet bit is always zero on a cold
reset, and is intended as a mechanism for the BIOS to determine the type
of a reset that occurred.
Set ColdRstDet=1 after all cores have been initialized, so that any
subsequent reset may be identified as warm/cold. A later patch will check
the value during mp_init.
