Subject: [PATCH net-next 10/12] dt-bindings: net: document bcmgenet WoL interrupt

A third interrupt cell can be provided to optionally specify
the interrupt used for handling Wake on LAN events.

Typically the wake up handling uses a separate interrupt
controller, so the interrupts-extended property is used to
accommodate this.
