[PATCH] dt-bindings: update OpenFirmware document links to devicetree.org

[Rob Herring]

The mirrors for old, but still referenced OF documents have disappeared.
A new mirror has been setup on devicetree.org at:

http://devicetree.org/open-firmware/home.html

Update the URLs in the binding documents with the new mirror.
