[PATCH 1/3] clk: mediatek: mt8183: Convert gate only drivers to mtk_clk_simple_*()

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

mtk_clk_simple_*() was added after the MT8183 clock drivers were merged.
They provide shared boiler plate for clock providers that only have
clock gates.

Convert many of the MT8183 clock drivers to mtk_clk_simple_*(). This
also adds proper driver removal support for them.

Since the mtk_clk_simple_probe() function allocates the clk_hw pointer
array based on .num_clks given, it effectively requires there are no
holes in the clock ID map. Check that the size of the array matches
the number of clocks with a static assertion.
