[ Upstream commit bd54ccc0f147019dac38e7841876a7415459b875 ]
The mtk_clk_register_pll_ops() currently frees the "pll" parameter.
The function has two callers, mtk_clk_register_pll() and
mtk_clk_register_pllfh(). The first one, the _pll() function relies on
the free, but for the second _pllfh() function it causes a double free
bug.
Really the frees should be done in the caller because that's where
the allocation is.
