Currently we retry if we don't detect an electrical link. This is pointless as all devices should respond in the given time. This patches removes this retry and just returns OPAL_HARDWARE if we don't detect an electrical link. This has the additional benefit of improving boot times on machines that have badly wired presence detect (ie. says a device is present when there isn't).
