There are two boards supported by this driver. One with 16-bit analog inputs and the other 12-bit analog inputs. Add a bit field flag, 'ai_is_16bit', to the boardinfo and remove the 'i_AiMaxdata' member. Use the new flag to initialize tne analog input subdevice maxdata correctly. For aesthetics, adjust the whitespace in the boardinfo declaration.
