OOT drivers build against multiple kernel. All kernel does not support the prod configurations. Add wrapper header for prod header as oot-prod which can be used by all OOT drivers for prod configurations. This new header implement the prod APIs as success if core kernel does not support the prod functionality. This will help to avoid any build and run time error.
