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.
