Add POWER_SUPPLY_PROP_CHARGE_COUNTER_EXT that stores accumulated charge
in nAh units as a signed 64-bit value.
Add generic support for signed 64-bit property values.

Ensure userspace reads an up-to-date value for charging status whenever the
charge source is updated. Avoid races where stale charging state may be
reflected in userspace until the next battery state poll.

When a new charge source is set, enable charging and set the charging
current, unless we've paused charging due to battery full or battery
health problems.

Alarmtimer may execute the monitor early in the resume sequence. Freeze the
monitor while suspended, and unfreeze after the battery charger and fuel gauge,
etc. drivers are resumed.

- Alarm Timer driver is suspended before battery driver, so alarm
timer was not changed to slow poll speed at suspend. Use PM
notifiers instead.
- If charger is connected, keep 1 min alarm timer.

If charger was connected and a charge source change event occurs such that
the charger is still connected (or a different charge source connected),
do not overwrite an existing state such as full or not-charging. Only
switch from discharging to charging on a charge source change event.

For reflecting board-level decisions on whether USB or AC charger
is connected, which may differ from charger power supply notion
of USB input path (which may be connected to an AC charger) vs.
AC input path.

Add a generic battery power supply and glue logic for talking to the
board battery driver. This driver handles common chores such as:
* periodic battery level and health monitoring
* kernel log reporting and other debugging features for key
properties provided by different charger, fuel gauge, etc.
components
* ensure properties such as battery health are made available to
userspace
* common processing for board-level battery/case temperature sensors
and policy for charging status based on battery health
Based on work by himihee.seo@samsung.com, ms925.kim@samsung.com, and
