Make this driver work a whole lot better.
- Get the initial mode from the prom settings and don't clobber the mode
  on open.
- Copy output into an internal ring buffer instead of accessing the tty
  outq directly in the interrupt handler.  This fixes a problem where
  garbage would show up in the output stream.
- Reset the console port completely and reprogram all the parameters
  before enabling it.  This fixes seemingly random hangs on startup
  when using a fast interrupt handler.
- Add minimal locking in place of spls.
- Remove dead code and minor cleanups.
