[media] v4l2-core: add code to check for specific ops This patch adds a v4l2_subdev_has_op() macro and a v4l2_device_has_op macro to quickly check if a specific subdev or any subdev supports a particular subdev operation. This makes it easy for drivers to disable certain ioctls if none of the subdevs supports the necessary functionality.
