spapr_pci: Add numa node id
This adds a numa id property to a PHB to allow linking passed PCI device to CPU/memory. It is up to the management stack to do CPU/memory pinning to the node with the actual PCI device. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> [dwg: Renamed property from "node" to "numa_node" to match the similar one in the pxb device] Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
