These names are also spread across several pieces of AMD64 and
Hypertransport documentation, since it illustrates hypertransport
graphs of different wiring quite nice. Still, it's unclear from a
technical point of view.

Should not be too hard, since we are not really using them heavily. I
still have some defines used in coherent_ht.c which should go away 
and replaced by something more sophisticated.
