dt-bindings: power: supply: Correct indentation and style in DTS example

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |'. Correct mixtures of the style or any other
indentations to use preferred 4-spaces.

No functional changes here, but saves some comments during reviews
of new patches built on the existing code.
