[PATCH v3 27/31] clk: mediatek: Unregister clks in mtk_clk_simple_probe() error path

Until now the mediatek clk driver library did not have any way to
unregister clks, and so all drivers did not do proper cleanup in
their error paths.

Now that the library does have APIs to unregister clks, use them
in the error path of mtk_clk_simple_probe() to do proper cleanup.
