cpu/intel/smm: Use CONFIG_SMM_TSEG_SIZE

An epic battle to fix Nehalem finally ended when we found an odd mask
set in SMRR. This was caused by a wrong calculation of TSEG size. It
was assumed that TSEG spans the whole space between TSEG base
and GTT. This is wrong as TSEG base might have been aligned down.

TEST: On X201, copied 1GiB from usb key to sd-card and verified.
