drm/i915: die, i915_probe_agp, die
Use the detection from intel-gtt.ko instead. Hooray! Also move the stolen mem allocator to the other gtt stuff in dev_prv->mem. v2: Chris Wilson noted that my error handling was crap. Fix it. He also said that this fixes a problem on his i845. Indeed, i915_probe_agp misses a special case for i830/i845 stolen mem detection.
