media: cobalt: do not register subdev nodes 

In the distant past the adv7604 driver used private controls. In order
to access them the v4l-subdevX nodes were needed. Later the is_private
tag was removed in the adv7604 driver and the need for v4l-subdevX
device nodes disappeared.

Remove the creation of those device nodes from this driver.

Note: the cobalt card is only used inside Cisco and we never actually
used the v4l-subdevX nodes for anything. So this API change can be done
safely without breaking anything.
