Remove obsolete public/API methods in chromium port.
Created attachment 71889 [details] Patch
This method was added in https://bugs.webkit.org/show_bug.cgi?id=48068 to prevent the chromium build breaking while an API change was made. Chromium has now rolled past that revision of webkit so this method is obsolete and can be removed.
