Enabled WIFI wakelocks, but reduced them + enabled powersuspend >>>

To Save power on screen OFF.

from dmesg on screen off
<4>dhd_early_suspend: enter
<4>dhd_set_suspend: force extra Suspend setting

on screen on
<4>dhd_late_resume: enter
<4>dhd_set_suspend: Remove extra suspend setting

using powersuspend code structure.

This should save some more power when WIFI is ON and allow fast notifications
from SYNC and apps.
