AXP803 PMIC features AC/USB/Battery power supplies.

As we have now the device tree bindings for them, add device tree
nodes for them.

No. You have added support for the AC and battery power supply drivers
in this patchset, not for USB.
But I added its device tree binding.
Yes and that is wrong. That would mislead users into thinking the usb
power supply is supported (since the dt binding is here) while it's not.

I would add the dt binding and the DT node only once it is supported.
