See the commit message :)

I can move this to util/virpci instead of conf/device_conf for
the time being if you prefer, but at some point we're going to
have to pick a place for *all* functions related to PCI addresses
and conf/device_conf is the most sensible option IMHO, seeing as
all other address types and related functions are defined there.
