clean these up (mostly rename bus_space_{tag,handle}_t variables) so that
this code makes equal sense for memory and I/O space, prefer to map the PCI front end via memory space (conditionalized on a patchable kernel variable), and do a bit of other random NetBSD-specific cleanup. (These changes were sent to Justin Gibbs on March 28.)
