Starting with Hyper-V PCI protocol version 1.3, the host VSP can send
PCI_BUS_RELATIONS2 and pass the vNUMA node information for devices on the bus.
The vNUMA node tells which guest NUMA node this device is on based on guest
VM configuration topology and physical device inforamtion.

The patch adds code to negotiate v1.3 and process PCI_BUS_RELATIONS2.

+ * hv_pci_devices_present2() - Handles list of new children
