staging: comedi: dnya_pci10xx: use attach_pci callback

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 the pci bus to find the pci_dev and the
need for the pci_dev_put() in the detach.
