nb/intel/nehalem: Remove the C native graphic init
Libgfxinit provides a better alternative to the native C init. While libgfxinit mandates an ada compiler, we want to encourage use of it since it is in much better shape and is actually maintained. This way libgfxinit also gets build-tested by Jenkins.
