amd/stoneyridge: Enable SMM in TSEG
Add necessary features to allow mp_init_with_smm() to install and
relocate an SMM handler.
SMM region functions are added to easily identify the SMM attributes.
Adjust the neighboring cbmem_top() rounding downward to better reflect
the default TSEG size. Add relocation attributes to be set by each
core a relocation handler.
Modify the definition of smi_southbridge_handler() to match TSEG
prototype.
