Hi,

This series cleans up the generic ADC battery driver and adds
devicetree support. The plan is to use the driver to add upstream
support for a handheld thermal camera.

Instead of reading and exposing the monitored battery data manually
I started the series with an addition to the power-supply core,
which allows automatic handling of the static battery information.
It simplifies the generic-adc-battery driver a lot and should also
be useful for other battery drivers.

Changes since PATCHv2:
 * collect more Reviewed-by (again skipped PATCH 1)
 * updated battery-info auto-exposure to only do it for TYPE_BATTERY
   power-supply devices.
 * Fix battery-info auto-exposure to avoid duplicated uevent variables
 * Added two more cleanup patches at the end of the series

Changes since PATCHv1:
 * collect Reviewed-by
   (I did not collect them for the auto-exposure because of the
   code changes)
 * always auto expose battery data (without opt-in)
 * update DT binding according to feedback
 * add temperature support
 * fix issues pointed out by the Intel build bot
  - move power_supply_battery_info_properties to power_supply_core.c
  - restore accidently removed EXPORT_SYMBOL for power_supply_get_property
