F2FS: cache not support labeling

<7>SELinux: initialized (dev mmcblk0p31, type f2fs), not configured for labeling
Fixed CRON Service, Fixes TRIM cron(read more) other minor bugs.

*Crond was getting killed, and no cron tasks run. now will run.
*TRIM must be used ONLY on wake state! never in deepsleep.
So i have added wakeup trigger, screen will be ON, TRIM RUN, Screen OFF.
Problem solved :)
*Fixed minir bugs with ondemand tuning set after init.d and more.
