Since topspin cards have a distinct vendor id, its possible they dont
need the board id at all.

What'd you like to do?
- Report empty board id (thats what current code does). User can follow
  the device link and use vendor id to figure out its a topspin card.
- Check topspin vendor id and report some hard-coded string in board_id.
- Check topspin vendor id and report some other field from the vpd.
