power: charger-manager: Hold wakeup event until userspace notice.
This is workaround to let userspace notice about battery's status
chaiging during suspend and resume. It holds wakeup event to prevent
system goes into sleep. Holding wakeup event time is heuristic value
and it could be varied.
To make this works, it needs CONFIG_PM_AUTOSLEEP kernel option.
