In order to do this, the main logic of clk_mtk_simple{probe,remove}() was moved to new static __clk_mtk_simple_{probe,remove}() functions that take as parameter a pointer to struct device_node because when registering the clocks from mtk-mmsys we want to pass a pointer to the clock driver's parent (which is, obviously, mtk-mmsys) struct device_node instead. As for the clock driver's platform data: for the devicetree case, we keep using the standard match_data mechanism, else we retrieve it from an id_table.
