dt-bindings: pinctrl: Allow values for drive-push-pull and drive-open-drain
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.
