hw/isa/piix3: Reuse piix3_realize() in piix3_xen_realize()

This is a preparational patch for the next one to make the following
more obvious:

First, pci_bus_irqs() is now called twice in case of Xen where the
second call overrides the pci_set_irq_fn with the Xen variant.

Second, pci_bus_set_route_irq_fn() is now also called in Xen mode.
