fs/dyn_sync_cntrl: dynamic sync control

The dynamic sync control interface uses Android kernel's unique early
suspend / lat resume interface.

While screen is on, file sync is disabled
when screen is off, a file sync is called to flush all outstanding writes
and restore file sync operation as normal.

powersuspend: new PM kernel driver for Android w/o early_suspend

Android early_suspend/late_resume PM kernel driver framework has been
