For systems with multiple servers and routed fabric, all northbridges get
assigned to the first server. Fix this by also using the node reported from
the PCI bus. For single-fabric systems, the northbriges are on PCI bus 0
by definition, which are on NUMA node 0 by definition, so this is invarient
on most systems.
Tested on fam10h and fam15h single and multi-fabric systems and candidate
for stable.
