The comedi (*attach) and (*auto_attach) functions are used to attach
legacy and PnP type devices to the comedi subsystem. If we can set the
dev->board_name before doing the attach, the drivers will not have to
worry about doing it.
Drivers that do additional probing can still change the dev->board_name
if necessary.
