A few platforms, at91 and tegra, use drive-push-pull and drive-open-drain with a 0 or 1 value. There's not really a need for values as '1' should be equivalent to no value (it wasn't treated that way) and drive-push-pull disabled is equivalent to drive-open-drain. So dropping the value can't be done without breaking existing OSs. As we don't want new cases, mark the case with values as deprecated.
