mtk_clk_simple_probe() is a function that registers mtk gate clocks and, if reset data is present, a reset controller and across all of the MTK clock drivers, such a function is duplicated many times: switch to the common mtk_clk_simple_probe() function for all of the clock drivers that are registering as platform drivers.
