====================
sfc: Add extra states for VDPA

For EF100 VDPA support we need to enhance the sfc driver's load and
unload functionality so that it can probe and then unregister its
network device, so that VDPA can use services such as MCDI to initialise
VDPA resources.

v2:
- Fix checkpatch errors.
- Correct signoffs.
