arm64: dts: allwinner: sun55i: Complete AXP717A sub-functions

Browse Source 
When the AXP717A PMIC is missing nodes for the sub-functions, the kernel
complains about not found nodes.

Add all the remaining nodes corresponding to the defined functions for
the dev boards, which have publicly available schematics to base this
change on. The battery charger on all of them are disabled. Also add
an "iio-hwmon" node to express some of the ADC channels as hwmon
sensors.
