[media] v4l2-ctrls: add a filter function to v4l2_ctrl_add_handler
With a filter function you can control more precisely which controls are added. This is useful in particular for radio device nodes for combined TV/Radio cards where you want to show just the radio-specific controls and not controls like brightness.
