staging: comedi: ke_counter: store the pci_dev in the comedi_device
Use the hw_dev pointer in the comedi_device struct to hold the pci_dev instead of carrying it in the private data. Since the pci_dev was the only thing in the private data, remove the struct, the devpriv macro, and it's allocation.
