staging: comedi: refactor comedi_parport driver and use module_comedi_driver
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.
