vfio: Add struct device to vfio_device
and replace kref. With it a 'vfio-dev/vfioX' node is created under the
sysfs path of the parent, indicating the device is bound to a vfio
driver, e.g.:
/sys/devices/pci0000\:6f/0000\:6f\:01.0/vfio-dev/vfio0
It is also a preparatory step toward adding cdev for supporting future
device-oriented uAPI.
Add Documentation/ABI/testing/sysfs-devices-vfio-dev.
