Revert "WIFI: do not use powersuspend for WIFI, it's has it's own PM triggers."

This reverts commit 2cbc2c8bfbcd43a9e0e894e289918498d2346ce6.

People reporting that WIFI drain mre power when suspended, right after this change.
and WIFI wakelock is a lot higher than before.

So revert this change.
Revert "Turn OFF HTC ASYNC_FSYNC code for all models."

This reverts commit 5b71591529853eccb150cd7a1ba4210e22c41a0e.

RESTORE HTC ASYNC, seems that it's was saving some power, and was
not the problem maker, it's was all in MMC code.
RESTORE MMC WAKE/SUSPEND Functions: MMC bug was in other commit.

This restores:

Need to deep test this changes.

Any way power usage was higher than with all this added. so restore it.
sched: Fix inaccurate accounting for real-time task

It is possible that rq->clock_task was not updated in put_prev_task()
in which case we can potentially overcharge a real-time task for time
it did not run. This is because clock_task could be stale and not
represent the exact time real-time task started running.

Fix this by forcing update of rq->clock_task when real-time task
starts running.

 */
Config Update + Cleanup READ MORE!

*Enabled bootloader bootstats for me to know how things works. once at boot.
*Set all ENCRYPT config to STOCK to fix DATA encryption by ROM, was broken.
*Disabled KERNEL DEBUG that had no active config under it any way.
