[media] v4l2-subdev: add registered_async subdev core operation
V4L2 sub-devices that are registered asynchronously have no way to know
when they have been registration with a V4L2 device but they might need
to take some action after this.
So let's add a callback that can be executed by the V4L2 async core to
allow sub-devices drivers to do any needed initialization that depends
on the registration.
