staging: comedi: ni_670x: use module_comedi_pci_driver

Browse Source 
Refactor the driver to use the module_comedi_pci_driver() helper.
This gets rid of some of the module boilerplate code.

For aesthetic reasons, rename the comedi_driver and pci_driver to
follow the convention of the other comedi pci drivers.
