This is different from the cpumux and mux type clks, for which all of the code are found in the same files. Move the functions that register multiple clks from a given list, mtk_clk_register_gates_with_dev() and mtk_clk_register_gates(), to clk-gate.[ch] to consolidate all the code for the gate type clks. This commit only moves code with minor whitespace fixups to correct the code style. Further improvements, such as internalizing various functions and structures will be done in later commits.
