cpu/x86/smm: Define single smm_subregion()

At the moment we only have two splitting of TSEG,
one with and one without IED. They can all use
same implementation.

Make configuration problems of TSEG region assertion
failures.

Rename file from stage_cache.c to tseg_region.c to
reflect it's purpose.
