[media] v4l2-subdev: add (un)register internal ops
Some subdevs need to call into the board code after they are registered
and have a valid struct v4l2_device pointer. The s_config op was abused
for this, but now that it is removed we need a cleaner way of solving this.
So this patch adds a struct with internal ops that the v4l2 core can call.
Currently only two ops exist: register and unregister. Subdevs can implement
these to call the board code and pass it the v4l2_device pointer, which the
board code can then use to get access to the struct that embeds the
v4l2_device.
It is expected that in the future open and close ops will also be added.
