[PATCH v2] cpufreq: loongson2: fix broken cpufreq

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.

	Changes since the first version
	(http://marc.info/?l=linux-kernel&m=137357177225034&w=2):

	- Changed the subject prefix. I guess this should be merged through
	  the cpufreq/PM instead of MIPS tree?

	- Added ACK from Viresh Kumar.
