[PATCH v3 3/4] PCI: Make host bridge interface publicly available

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

Allow PCI host bridge drivers to use the new host bridge interfaces to
register their host bridge.
