Subject: cpufreq: loongson2: fix regression related to clock management

From: Aaro Koskinen <aaro.koskinen@xxxxxx>

commit f54fe64d14dff3df6d45a48115d248a82557811f upstream.

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.
