- Convert these bus drivers to make use of the newly introduced set of

ofw_bus_gen_get_*() for providing the ofw_bus KOBJ interface in order
  to reduce code duplication.
- While here sync the various sparc64 bus drivers a bit (handle failure
  to attach a child gracefully instead of panicing, move the printing
  of child resources common to bus_print_child() and bus_probe_nomatch()
  implementations of a bus into a <bus>_print_res() function, ...) and
  fix some minor bugs and nits (plug memory leaks present when attaching
  a bus or child device fails, remove unused struct members, ...).

Additional testing by:	kris (central(4) and fhc(4))
