[PATCH v3 1/3] dt-bindings: leds: aw2013: Document interrupt

[Stephan Gerhold]

AW2013 has an optional interrupt pin "INTN" which is used to report
completion of started operations (e.g. power up or LED breath effects).
The driver does not use it (yet) but it should be described for
completeness inside the DT schema.
