MIPS: loongson2_cpufreq: Fix CPU clock rate setting mismerge
During 3.16 merge window, parts of the commit 8e8acb32960f (MIPS/loongson2_cpufreq: Fix CPU clock rate setting) seem to have been deleted probably due to a mismerge, and as a result cpufreq is broken again on Loongson2 boards in 3.16 and newer kernels. Fix by repeating the fix. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Cc: stable@vger.kernel.org # 3.16 Cc: Rafael J.
