staging: comedi: das08: Use module_comedi_{pci_, }driver

If PCI boards are supported, use the module_comedi_pci_driver() macro to
register the module as a comedi driver and a PCI driver.  Otherwise, if
ISA (or PC/104) boards are supported, use the module_comedi_driver()
macro to register the module as a comedi driver.  Otherwise, this is
only a helper module for an external comedi driver (das08_cs).
