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.
