Convert this PCI driver to use the comedi PCI auto config attach
mechanism by adding an attach_pci callback function. Since the
driver does not require any external configuration options, disable
the legacy attach by making the attach simply return -ENOSYS. This
removes the need to walk to pci bus to find the pci_dev and the

staging: comedi: make attach handler optional
Some low-level Comedi drivers no longer support manual configuration of
devices with the COMEDI_DEVCONFIG ioctl (used by the comedi_config
program). For those drivers, the 'attach_pci' or 'attach_usb' handler
will be set in the struct comedi_driver to configure devices

comedi_usb_auto_config()). Their 'attach' handlers are redundant but
the the comedi core module currently requires it to be set.
