adrian 90a75924ee [arswitch] extend the debug support to be configurable at runtime.
* remove the DEBUG ifdef; defining it is too far reaching throughout
  the whole system;
* add a bitmask in the softc for controlling debugging;
* .. enable said debugging as a sysctl;
* add bitmaps for register access, reset and vlans.

TODO:

* Now that the debug statements are configurable, we definitely could
  do with more debugging
* Move the debugging into the top-level etherswitch driver and have
  sub-drivers obey.
