Yes, though the new PCIe host/bridge drivers with DT support all seem to call
pci_common_init at probe with a non-statically defined hw_pci with the
nr_controllers always set to 1 (meaning that pci_common_init can be called
multiple times). Also hw_pci now has a field for private_data anyway which
breaks this assumption...

Is there an argument for removing hw_pci or at least .nr_controllers and call
pci_common_init multiple times (as is potential current use case for DT PCI
drivers)?
