I'm converting from qdev_create()/qdev_init_nofail() to
qdev_new()/qdev_realize_and_unref(); recent commit "qdev: New
qdev_new(), qdev_realize(), etc." explains why.
PCI devices use qdev_create() through pci_create() and
pci_create_multifunction().
Provide pci_new(), pci_new_multifunction(), and
pci_realize_and_unref() for converting PCI devices.
