This looks like another hard code. In a perfect world, we look at each
link of each CPU, check and remember what is connected to it, deciding
on the information we get from the northbridge, like whether the link is
coherent or non-coherent.
Currently we grab the information from the hypertransport graph that we
need for the next action, but we don't seem to be able to fully describe
the graph and optimally traverse it.
