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.
