PHB4 devices and PCI devices can now be added to the powernv9 machine
using:
-device pnv-phb4-pec,chip-id=0,index=0
-device nec-usb-xhci,bus=pci.0,addr=0x0
In case of user created devices, a lookup on 'chip-id' is required to
assign the owning chip.
To be noted, that the PEC PHB4 devices can add more than one PHB4
devices:
* PEC0 provides 1 PHB (PHB0)
* PEC1 provides 2 PHBs (PHB1 and PHB2)
* PEC2 provides 3 PHBs (PHB3, PHB4 and PHB5)
