media: v4l2-dev: Add v4l2_device_register_ro_subdev_node()
Add to the V4L2 core a function to register device nodes for video
subdevices in read-only mode.
Registering a device node in read-only mode is useful to expose to
userspace the current sub-device configuration, without allowing
application to change it by using the V4L2 subdevice ioctls.
