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.
