staging: comedi: Add helper macro for comedi_driver boilerplate
Introduce the module_comedi_driver macro which is a convenience
macro for comedi driver modules similar to module_platform_driver.
It is intended to be used by drivers where the init/exit section
does nothing but register/unregister the comedi driver. By using
this macro it is possible to eliminate a few lines of boilerplate
code per comedi driver.
