Instead of letting each driver call of_node_put do it centrally in the loop that also calls the CLOCKSOURCE_OF_DECLARE callbacks. This is less prone to error and also moves getting and putting the references into the same function. Consequently all respective of_node_put calls in drivers are removed.
