powerpc ps3bus: Use bus_generic_rman_*

[jhb]

Summary

• Split out part of ps3bus_activate_resource into a ps3bus_map_resource method.

• Implement ps3bus_unmap_resource via pmap_unmapdev.

• Use bus_generic_rman_* to add bus_adjust_resource, bus_deactivate_resource, and bus_release_resource methods.

Looks fine. I have no way to test, though.

I wonder if the PS3 option might be past its prime and time to retire.
I couldn't figure out how to run it for my kboot work, for example.

Agreed, and our resident maintainer, Nathan, is no longer available.

I've had two offers to test PS/3 based on people having PS/3 sitting in their closet, not based on people still running it day to day.
