- Implement bus_map/unmap_resource pulling bits from the previous
ofw_pcib_activate/deactivate_resource. One difference here is that
the bus_unmap_resource implementation uses bus_space_unmap instead
of pmap_unmapdev as a complement to the existing use of bus_space_map.
- Use bus_generic_rman_* in various routines for memory and I/O port
resources.
- Use pci_domain_* for PCI_RES_BUS in
ofw_pcib_activate/deactivate_resource.
