HP300 DIO bus updates from Kars de Jong:
  - Removed kludges for internal HPIB, no need to handle it as a DIO device
  - Removed dio_scodetoviraddr() and introduced dio_scodetophysaddr() instead,
    to be able to support DIO-II
  - Removed trailing white space
  - Changed error return code of dio_find() from 0 to -1, since select code 0
    is a valid select code
  - Added support for DIO-II
  - Fixed problem with DIO_ENCODE_ID()
