of: add iterator for overlays
Device tree overlays (the dto files) may contain multiple fragments for different target nodes. Each fragment contains a __overlay__ node that is applied to target node specified in the fragment. Add a helper to call a function for each fragment in a device tree overlay to avoid having device tree overlay internal information in other modules.
