Same comment as for patch 10: If we leave this out of the pci_create_host_bridge
argument but set it later, þe interface becomes simpler for callers that
don't have custom pci_host_bridge_ops.

This would break your phb_prepare() callback, but I assume a host driver
can just make a direct function call before entering pci_create_host_bridge
for this. Let me know if I'm missing something here.
