nb/intel/sandybridge: Limit GFX workaround to Sandy Bridge
The touched workaround for Sandy Bridge reserves two memory regions that
could cause graphics corruption if mapped by the integrated graphics
device. To the best of our knowledge, the workaround is not needed for
Ivy Bridge revisions.
Tested on kontron/ktqm77 (Ivy Bridge): Booted Linux and checked the
memory regions are not reserved. Couldn't test on Sandy Bridge, due to
lack of hardware.
