gpio: of: Scan available child node for gpio-hog
Look for child node which are available when iterating for gpio hog node for request/set GPIO initial configuration during OF gpio chip registration. All it really does is make it possible to set status = "disabled"; in the hog nodes, and then they will not be applied.
