Revert "sched: LOAD_FREQ (4*HZ+61) avoids loadavg Moire"

This reverts commit 7d03b824de1016794cba25672e5ac629534dfce5.

Some strange hangs, screen is freezing for 2~4sec without any dmesg
logs, never was before. so i guess this should go out.
MSM THERMAL: allow Max 78C for CPU TEMP. and 79 for CORE ON/OFF
BACKLIGHT CONTROL v5: before changing backlight, check current LUX.

If we have higher than 100LUX then dont make any visable change.
Driver will wait till device is in dark.
