staging: comedi: ni_routes: Refactor ni_find_valid_routes()

Browse source

Split out the loops in `ni_find_valid_routes()` into separate functions:

* ni_find_route_values(device_family) to find the list of route values
  for a device family (e.g "ni-mseries"); and
* ni_find_valid_routes(board_name) to find the set of valid routes for a
  board name.

The functions above return `NULL` if the information is not found (as we
do not currently have the routing information available for all
supported boards).
