power: charger-manager: Support different polling mode for sleep state.
Add additional polling mode for sleep state to define different mode with
normal state. With this change, charger-manager can work differently in
normal state or sleep state. e.g, polling aways for normal and polling
only when charing for sleep. If there is no defined polling mode for
sleep state it just follows the normal state's.
In addition to, polling rate is still same in sleep.
