[PATCH 04/31] clk: mediatek: gate: Implement unregister API

[Miles Chen]

> The gate clk type within the MediaTek clk driver library only has a
> register function, and no corresponding unregister function. This
> means there is no way for its users to properly implement cleanup
> and removal.
> 
> Add a matching unregister function for the gate type clk.
