power_supply: add battery_info and battery_info_id parameters

Add the following power supply parameters so that some battery
information can be stored based on the id passed and notified to
a power supply. These parameters will be typically used by the
userspace to notify some stored battery information back to the
driver to do some calculations.

- POWER_SUPPLY_PROP_BATTERY_INFO
- POWER_SUPPLY_PROP_BATTERY_INFO_ID

For example, if the battery_info_id is 1, value written to the
battery_info parameter will be treated as SOC (state of charge).
