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.

power: android-battery: Add USB and AC battery power supplies

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.

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.

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: 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.
