[PATCH V2 00/15] Add Battery and USB Supply for AXP717

Add support for monitoring the USB charger and battery charger on the
AXP717 PMIC. This required some driver refactoring of the axp20x USB
and battery charger as the AXP717 is somewhat different but can still
benefit from some common elements.

Note that as of now the charging current now value may be incorrect as
the scale and offsets were not documented in the datasheet. I suspect
the scale is 1 and the offset is somewhere around 450mA though.

Changes from V1:
- Refactored against mainline to remove BOOST pre-requisite.
- Corrected commit subjects for DT bindings.
- Split refactoring and AXP717 support into different patches.
- Added IRQ for VBUS over voltage. There appears to be a bug
with the VBUS fault IRQ because it is assigned IRQ num 0.
- Corrected battery driver to report POWER_SUPPLY_PROP_VOLTAGE_MIN
and POWER_SUPPLY_PROP_VOLTAGE_MAX instead of *_DESIGN.
