 *
 *   @b Arguments
 *   @verbatim
            hPwrdwn         Pointer to the object that holds reference to the
                            instance of PWRDWN requested after the call 

            config          Pointer to the config structure containing the
                            device register values
     @endverbatim
 *
 *   <b> Return Value </b>  CSL_Status
 *   @li                    CSL_SOK             - Configuration successful
 *   @li                    CSL_ESYS_BADHANDLE  - Invalid handle
