This patch centralizes the MSEG location calculation. In the current
implementation, the calculation happens in smm_module_loader and
mp_init. When smm_module_loaderv2 was added, this calculation became
broken as the original calculation made assumptions based on perm_smbase.
The calculation is now located in smm_subregion (tseg_region.c), as the
MSEG is located within the TSEG (or SMM);
These patches have been tested on a Purism librem-l1um server.
