Get out the roto-rooter and clean up the abuse of nexus ivars by the

i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.
