cpu/amd/agesa/family15tn: Add initial support for SMM mode
This is the minimal setup needed to be able to execute SMI handlers.
Only support for ASEG handlers is added, which should be sufficient
for Trinity (up to 4 cores).
There are a few hacks which need to be introduced in generic code in
order to make this work properly, but these hacks are self-contained.
They are a not a result of any special needs of this CPU, but rather
from a poorly designed infrastructure. Comments are added to explain
how such code could be refactored in the future.
