clk: mediatek: Switch to mtk_clk_simple_probe() where possible

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.
