versatile_pci: Update to realize and instance init functions
Update the Versatile PCI controller to use a realize function rather than SysBusDevice::init. To reflect the fact that the 'realview_pci' class is taking most of its implementation from 'versatile_pci' (and to make the QOM casts work) we make 'realview_pci' a subclass of 'versatile_pci'.
