The GuC uses a special mapping for the upper end of the Global GTT, similar to the way it uses a special mapping for the lower end, so exclude it from our drm_mm to prevent us using it. v2: Rename to reflect that it is unmappable similar to the region at the bottom of the GGTT, and couple it into the assertion that we don't feed unmappable addresses to the GuC.
