which bustype should be attached with a specific call to config_found() (from a "mainbus" or a bus bridge). Do it for isa/eisa/mca and pci/agp for now. These buses all attach to an mi interface attribute "isabus", "eisabus" etc., and the autoconf framework now allows to specify an interface attribute on config_found() and config_search(), which limits the search of matching config data to these which attach to that specific attribute. So we basically have to call config_found_ia(..., "foobus", ...) where such a bus is attached. As a consequence, where a "mainbus" or alike also attaches other devices (eg CPUs) which do not attach to a specific attribute yet, we need at least pass an attribute name (different from "foobus") so that the foo bus is not found at these places. This made some minor changes necessary which are not obviously related to the mentioned buses.
