staging: comedi: remove boardtype macro in the ni_atmio16d driver

Browse Source 
The 'boardtype' macro depends on having a local variable with
a magic name. The CodingStyle document suggests not doing this
to avoid confusion. Remove the macro and use the comedi_board()
inline helper to get the dev->board_ptr information.
