- Rename UPA_BUS_SPACE to NEXUS_BUS_SPACE; besides an UPA bus, nexus(4)

may also reflect a Fireplane/Safari or JBus bus (or a virtual bus which
  in turn reflects a JBus bus or something like that...).
- In the both the sparc64 and sun4v bus_machdep.c use __FBSDID.
- Spell SBus the official way in comments.
- Replace hardcoded function names (all of which were actually outdated)
  in panic and status strings with __func__.
- Fix whitespace nits.
