nb/intel/*: Use 2M TSEG instead of 8M on pre-arrandale hardware

8M was set in the assumption that at least 4M was needed for IED
(Intel Enhanced Debug) , but this is not true.

The SMRR MTRR's need to have TSEG aligned to its size which is easier when TSEG
is only 2M. Also at most 6M of RAM more becomes available for use.
