I'd like to do that for all drivers in drivers/pci/host, but leave the
ones for the legacy platforms in arch/arm alone, in particular the ones
that use nr_controllers != 1.
We should be able to remove pci_common_init_dev() and directly probe
all devices that are using that, while we keep pci_common_init()
around for the legacy case that also does not have a parent device.
