PM / devfreq: exynos5422: remove build warningstizen_4.0.m2_releasetizen_4.0.IoT.p2_releasetizen_4.0.IoT.p1_releasesubmit/tizen_4.0/20171011.054609accepted/tizen/4.0/unified/20171011.150047tizen_4.0tizenaccepted/tizen_4.0_unified

Remove build warnings including unused-varable and
aggressive-loop-optimizations.

After the commit 642f6f62a65e ("PM / devfreq: exynos5422: remove
unused frequiencies"), the length of freq array is less than
LV_END, so it should use ARRAY_SIZE() instead of LV_END.
