[PATCH v2 19/31] clk: mediatek: Add mtk_clk_simple_remove()

[Chen-Yu Tsai <wenst@chromium.org>]

In commit c58cd0e40ffa ("clk: mediatek: Add mtk_clk_simple_probe() to
simplify clock providers"), a generic probe function was added to
simplify clk drivers that only needed to support clk gates. However due
to the lack of unregister APIs, a corresponding remove function was not
added.

Now that the unregister APIs have been implemented, add aforementioned
remove function to make it complete.
