cpu/amd/model_10xxx: Do not initialize SMM memory if SMM is disabled
In the wake of the recent Intel "Memoy Sinkhole" exploit a code review of the AMD SMM code was undertaken. While native Family 10h support does not appear to be affected by the same SMM flaw, it also does not require SMM to function. Therefore, the SMM memory range initialization should only be executed if SMM will be used on the target platform.
