[PATCH 05/10] clk: align error return of basic clks registeration

[shawn.guo@linaro.org (Shawn Guo)]

clk_register_gate and clk_register_divider return NULL for error,
which is aligned with clk_register function.  But clk_register_mux
and clk_register_fixed_rate return ERR_PTR.  Change them to return
NULL for better aligning with other registeration functions.
