This driver is an example of how to write a Comedi driver and includes some code for handling PCI devices, but not very much. It calls `comedi_pci_auto_config()` at PCI probe time. That normally expects to call the comedi driver's `auto_attach()` hook (or the deprecated `attach_pci()` hook), but will fall back to using the `attach()` hook that should only be used for attaching devices "manually" via the `COMEDI_DEVCONFIG` ioctl. Add an `auto_attach()` hook (`skel_auto_attach()`) to handle auto-attachment of supported PCI devices. Add comments to the `attach()` hook (`skel_attach()`) to indicate that it shouldn't generally allow PCI devices to be attached that way (and probably isn't needed at all for PCI-only Comedi drivers). Add code to the `detach()` hook (`skel_detach()`) to disable PCI devices enabled by the `auto_attach()` hook. `skel_auto_attach()` calls new function `skel_find_pci_board()` to find a matching element in `skel_boards[]`. PCI device ID information has been added to `skel_boards[]` to give the function something to look for. Remove the `pci_dev` member of `struct skel_private` as drivers now use the `hw_dev` member of `struct comedi_device` to get at the PCI device.
