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.
