clk: mediatek: clk-mtk: Register MFG notifier in mtk_clk_simple_probe() 



In preparation for commonizing topckgen probe on various MediaTek SoCs
clock drivers, add the ability to register the MFG MUX notifier in
mtk_clk_simple_probe() by passing a custom notifier register function
pointer, as this function will be slightly different across different
SoCs.
