power: android-battery: use freezable workqueue for monitor

monitor while suspended, and unfreeze after the battery charger and fuel gauge,
etc. drivers are resumed.

power: android-battery: Fix battery alarm timer not modified at suspend
- 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.

power: android-battery: leave full/not-charging status when charger re-sensed
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.

power: android-battery: use 1/10th deg C units for temperature
Same units as power_supply, don't need 1/10000 deg C and conversion
is error-prone.

For reflecting board-level decisions on whether USB or AC charger

of USB input path (which may be connected to an AC charger) vs.
AC input path.

power: android battery: add generic android battery driver
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
joshua.chang@samsung.com.
