Subject: [PATCH 03/31] clk: mediatek: gate: Internalize clk implementation
struct mtk_clk_gate and mtk_clk_register_gate() are not used outside of
the gate clk library. Only the API that handles a list of clks is used
by the individual platform clk drivers.
Internalize the parts that aren't used outside of the implementation.
