Revert "Dynamic FSync control"

This reverts commit b459d9c1d103f37f5de11a5903c012e51c928c48.
dyn_sync_cntrl: dynamic sync control 1.1

The dynamic sync control interface uses Android kernel's unique early
suspend / late 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.
dynamic fsync: add reboot notifier to force flush outstanding data + add kernel panic notifier to force flush outstanding data

This should further prevent data corruption from kernel panics and
forced reboots

bump version to 1.2
