Add support to run SMM handler in TSEG instead of ASEG
Traditionally coreboot's SMM handler runs in ASEG (0xa0000),
"behind" the graphics memory. This approach has two issues:
- It limits the possible size of the SMM handler (and the
number of CPUs supported in a system)
- It's not considered a supported path anymore in newer CPUs.
