Problem description:
Powerpc has sparse node numbering, i.e. on a 4 node system nodes are
numbered (possibly) as 0,1,16,17. At a lower level, we map the chipid
got from device tree is naturally mapped (directly) to nid.

Interesting thing to play with, I'll try to test it on my POWER7 box,
but it doesn't have the OPAL layer :(

Note that it's also interesting to try it under PowerVM, with odd NUMA
topologies and report any issues found :)
