power: Turn Off remote sync of clock during suspend stress test

This patch will fix issues seen during suspend_stress_test such as:
2016-03-19T12:12:40.078192-07:00 wlan0: associated
2016-03-19T12:12:45.792246-07:00 Going to suspend-to-RAM state
2016-03-19T12:12:45.847019-07:00 Explicit sync
2016-03-19T12:12:45.117888-07:00 last active wakeup source: 00:02
2016-03-19T12:12:45.118318-07:00 Aborting suspend, wake event received

Remote sync of time happens immediately after the network comes up.
The time taken from resume of wlan and getting an IP is ~5 sec.
Hence, sync of hwclock and writing in rtc for wakealarm happens at
almost same time (when wake_interval=5).
This may cause spurious wake event and thus abort suspend.
