Squashed Faux dynamic sync control commits

fs/dyn_sync_cntrl: dynamic sync control

The dynamic sync control interface uses Android kernel's unique early

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.
