Uwe Kleine-König b3bc72757e clk: mediatek: Make mtk_clk_pdev_remove() return void 
This function returns 0 unconditionally. Make it return no value instead
and convert the drivers making use of it to platform_driver's
.remove_new().

This makes the semantics in the callers of mtk_clk_simple_remove() clearer
and prepares for the quest to make platform driver's remove function return
void. There is no semantic change.
