Add power-off alarm support in timerfd. System will power on 1 minute earlier than expected alarm time. However, if system power off time is not 1 minute earlier than expected alarm time, system needs to power on in 15 seconds MTK-Commit-Id: 8257e83370ab837c0dc253025ca57ac55e8213b5 Change-Id: Ic9d28b2381ae5616a0d5e2fa69e6c199462f2294 Signed-off-by: andrew.yang <andrew.yang@mediatek.com> CR-Id: ALPS04820396 Feature: Power-Off Alarm (cherry picked from commit 666ade8c895ab8f9944bb551e2616985a2d713f6) (cherry picked from commit 17273a7b5599e6c06fe3eb6c916b6894ecc58f96)
