add pci bridges by default for qemu > 2.3

Browse Source 
pci bridge are not hot-unplugglable,
which can give us live migration problem,
if we hot-unplug a device on pcibridge 1 or 2, we don't create the pci bridge on target guest

and pci bridge hotplug is not working on all os (windows for example).

So it's better to always add them at startup.
