[PULL 21/34] ppc/pnv: Introduce support for user created PHB3 devices |

PHB3 devices and PCI devices can now be added to the powernv8 machine
using :
-device pnv-phb3,chip-id=0,index=1 \
-device nec-usb-xhci,bus=pci.1,addr=0x0
The 'index' property identifies the PHB3 in the chip. In case of user
created devices, a lookup on 'chip-id' is required to assign the
owning chip.
