Add a new macro, CLK_FIXED_FACTOR_HWS, that can take an array of pointers to struct clk_hw, instead of a string, as its parent. Taking an array instead of a direct pointer allows the reuse of the array for multiple clks, rather than having one compound literal with the same contents allocated for each clk declaration.
