Uwe Kleine-König 61ca6ee782 clk: mediatek: Make mtk_clk_simple_remove() return void
__mtk_clk_simple_remove() and so also mtk_clk_simple_remove() return
zero unconditionally. Make them 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.
