Commit 42913c799 (MIPS: Loongson2: Use clk API instead of direct dereferences) broke the cpufreq functionality on Loongson2 boards: clk_set_rate() is called before the CPU frequency table is initialized, and therefore will always fail. Fix by moving the clk_set_rate() after the table initialization. Tested on Lemote FuLoong mini-PC.
