nb/intel/gm45: Put stage cache in TSEG
TSEG is not accessible in ring 0 after it is locked in ramstage, in
contrast with cbmem which remains accessible. Assuming SMM does not
touch the cache this is a good region to cache stages.
Tested on Lenovo thinkpad X200: on cold boot the external stage cache
gets created and the cached ramstage gets successfully used on the S3
resume path.
