dt-bindings: power: supply: rt5033-battery: Apply unevaluatedProperties

Additionally to the already available ref "power-supply.yaml", replace
"additionalProperties: false" by "unevaluatedProperties: false". Otherwise,
when referencing rt5033-battery in an example, message "'power-supplies' does
not match any of the regexes: 'pinctrl-[0-9]+'" will be returned.

dt-bindings: power: supply: Add DT schema for richtek,rt5033-battery

The RT5033 PMIC provides a simple fuel gauge via I2C.
Add a DT schema to describe how to set it up in the device tree.

Note that although RT5033 is a MFD with lots of functionality
(also charger, regulator, LEDs, ...) the fuel gauge has a separate
I2C bus and is not part of the MFD.
