[0/3] ppc/pnv: Support sparse NUMA memory addresses

IBM Power machines put NUMA node RAM at fixed addresses per node,
rather than packing it densely from address 0. This series implements
support for this by allowing machines to override the core NUMA
memory container packing, and add their own RAM regions to the
system memory space.

Thanks,
Nick
