northbridge/sch: don't overwrite hightables with GPU / TSEG memory
Without this, the hightables are placed just before the end of memory. However we might have the GPU memory located at the exact same spot, that is in the last 4 MiB. So without this patch, this area won't remain marked as "CONFIGURATION TABLES" within coreboot's memory table but becomes "RESERVED" because it is part of the PCI(2,0) device.
