[0/6] Convert remaining power-supply DT bindings to YAML

Hi,

Let's get rid of the remaining three non-YAML power-supply binding files.

1. charger-manager
   I initially skipped this, since the binding is quite complex.
   It turned out a basic yaml binding is not that complex.
   This does not check for supplies matching cm-regulator-name,
   but that should be fine considering this is a legacy binding.

2. max8925_battery.txt
   I initially skipped this, since it does not have a compatible
   node. This converts the MFD binding file
   compatible value. It needs to be described in the PMIC binding
   file, which has not yet been converted.

3. stericsson,ab8500-battery.txt
   This also describes a node below the PMIC, which does not have
   its own compatible value. The same applies.

I tested the series using dt-validate 2021.3.dev6+g38efe3f and nothing
is reported when running any of the following

for file in Documentation/devicetree/bindings/mfd/stericsson,ab8500.yaml \
            Documentation/devicetree/bindings/mfd/maxim,max8925.yaml \
	    Documentation/devicetree/bindings/power/supply/charger-manager.yaml ;
do
	make -s -j4 dtbs_check DT_SCHEMA_FILES=$file
	make -s -j4 dt_binding_check DT_SCHEMA_FILES=$file
done

Merging notes:
 * The ARM DTS changes can be merged independently. The DTS changes should be
   compatible with existing drivers and existing binding documenting.
 * The last patch depends on eb917497734c ("dt-bindings: power: supply: ab8500:
   Convert to DT schema format") queued into power-supply's for-next branch for
   v5.13. The change is not critical, so it can wait for 5.14.
    
Thanks for reviewing it,
