clk: Fix pointer casting to prevent oops in devm_clk_release()

clk: Fix pointer casting to prevent oops in devm_clk_release()

commit c643c44d2f44392a6d5f7b9254ab7872792431f5 upstream.

The release function is called with a pointer to the memory returned by
devres_alloc(). I was confused about that by the code before the
generalization that used a struct clk **ptr.
