[PATCH 26/79] staging: comedi: das16: cleanup dev->board_name usage

[H Hartley Sweeten]

This legacy driver does no additional probing so the dev->board_name
will already be properly initialized by the comedi core before calling
the (*attach) function.

Remove the unnecessary initialization of dev->board_name and use it
when requesting the resources instead of the open-coded strings.
