Move the module_init/module_exit routines and the associated
struct comedi_drive to the end of the source. This is more
typical of how other drivers are written and removes the need
for the forward declarations.
Convert the driver to use the module_comedi_driver() macro
which makes the code smaller and a bit simpler.

More refactoring needs to be done to remove the remaining
forward declarations. Doing that is this patch makes it
difficult to review.
