The X-Powers AXP20X and AXP22X PMICs have an AC entry to supply power to
the board. They have a few registers dedicated to the status of the AC
power supply.
This adds the DT binding documentation for the AC power supply for
AXP20X and AXP22X PMICs.

Add a binding for the regulator which controls the OTG chargepath switch.
The OTG switch gets its power from pm8941_5vs1, and that should be
expressed as a usb_otg_in-supply property in the DT node for the
charger driver. The regulator name is "otg-vbus".

The bq27xxx binding is a standard i2c style binding, however the
deprecated compatible fields and different revisions warrant its own
documentation.

It is possible to verify AC adapter presence via a register read, without
any physical connection to the ACOK pin on the charger. Allow this.

If the ac-detect gpio does not support interrupts, provide a fallback
to poll the gpio at a configurable interval.

The ACOK pin on the bq24735 is active-high, of course meaning that when
AC is OK the pin is high. However, all Tegra dts files have incorrectly
specified active-high even though the signal is inverted on the Tegra
boards. This has worked since the Linux driver has also inverted the
meaning of the GPIO. Fix this situation by simply specifying in the
bindings what everybody else agrees on; that the ti,ac-detect-gpios is
active on AC adapter absence.

Due the driver improvements, update the properties,
- Remove "active-semi,check-battery-temperature" property.
- Add the properties, "active-semi,irq_gpio"
and "active-semi,lbo-gpios".
- As act8945a-charger is regarded as a sub-device, update
the compatible and examples.

Currently the power supply device tree documentation is spread
in .../bindings/power_supply and .../bindings/power. This
unifies the files for chargers and battery fuel gauges in
.../bindings/power/supply and the ones for system reset/shutdown
in .../bindings/power/reset (same structure as used for the
drivers itself).
