This adds a struct v4l2_device to the go7007 device struct and registers it during v4l2 initialization. The v4l2_device registration overwrites the go->dev device_data, which is a struct usb_interface with intfdata set to the struct go7007. This changes intfdata to point to the struct v4l2_device inside struct go7007, which is what v4l2_device_register will also set it to (and warn about non-null drvdata on register.) Since usb disconnect can happen any time, this intfdata should always be present.
