marius c27e004e36 - Use the newly introduced pcib_mtx spin lock to lock psycho_ce(),
allowing it to be a filter/"fast" handler. Locking the interrupt
  handlers with a spin lock is mainly a requirement in schizo(4)
  but as we ought to register the spin lock anyway it should not
  hurt to take advantage of it in psycho(4).
- Pass both a driver_filter_t and a driver_intr_t argument to
  psycho_set_intr(), allowing to get rid of the FAST interrupt
  flag hack.
- Don't register the over-temperature interrupt handler as filter/
  "fast" handler so shutdown_nice() can acquire the process lock.
- Use bus_{read,write}_8() instead of bus_space_{read,write}_8()
  in order to get rid of sc_bushandle and sc_bustag in the softc.
- Correct the debug output for adjusting the subordinate bus number.
- Remove the banal and outdated above psycho_filter_stub().
- Fix some white space nits.
