nb/intel/ironlake: Reserve gap betwen TSEG and BGSM

There may be a gap between TSEG and the graphics stolen memory due to
the alignment done in `raminit.c`. If we allocate MMIO resources in
this range, it misbehaves unpredictably, so reserve it.

TEST=Booted Thinkpad X201s, allocated resources are above TOLUD.
