The USB charger status can be notified before the charger driver registers the USB phy notifier, so we should check the charger status in probe() in case we missed the USB charger notification.

Since the USB notifier context is atomic, we can not start or stop charging in atomic context. Thus this patch adds one work to help to charge or discharge. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

Use only one poweroff function and adapt it to work for both scenarios (with LPDDR or not). The assignement of pm_power_off was moved at the end of probe after all initializations are OK. This patch adapt the idea from commit 4e018c1e ("power: reset: at91-poweroff: use only one poweroff function").

The internal resistance of a battery is not a constant in its life cycle, this varies over the age of the battery or temperature and so on. But we just want use one constant battery internal resistance to estimate the battery capacity. Thus this patch introduces one property to present the battery factory internal resistance for battery information.
