staging: comedi: das08.h: make self-reliant
The Comedi "das08.h" header file is included by drivers for the
ComputerBoards/MeasurementComputing and Keithley Metrabyte boards in the
DAS08 series. It does not compile cleanly when it is the first header
included by the ".c" file. It uses `struct comedi_device *` in the
parameter list of a function prototype, so just declare `struct
comedi_device` as an incomplete type. It also uses `bool`, so include
<linux/types.h> to declare it.
