cpu/amd/agesa/family15tn: Add initial support for SMM mode

Hardware / Coreboot - Alexandru Gagniuc [gmail.com] - 16 April 2014 16:42 UTC

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.
