[PATCHv3 00/14] Add DT support for generic ADC battery

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
