mca: add integrated device bus matching
The MCA bus has a few "integrated" functions, which are effectively virtual slots on the bus. The problem is that these special functions don't have dedicated pos IDs, so we have to manufacture ids for them outside the pos space ... and these ids can't be matched by the standard matching function, so add a special registration that requests a list of pos ids or a particular integrated function.
