[PATCH] dt-bindings: pwm: Correct indentation and style in DTS example

[Krzysztof Kozlowski]

DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

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