[PATCH 1/3] dt-bindings: net: wireless: qcom: ath10k: Document LED node support

[Christian Marangi]

Ath10k based wifi cards can support a LED connected via GPIO internally.
The LED is configured used WMI call. Document support for the LED node
controllable standard LED bindings.

While at it adds also an example for PCIe where LED is commonly
connected and used on routers.
