[PATCH 1/4] dt-bindings: Update iProc GPIO bindings

[Ray Jui <ray.jui@broadcom.com>]

Update the iProc GPIO binding document to add a new optional property
'brcm,pinconf-func-off' that allows certain PINCONF parameters to be
disabled in certain iProc SoCs where these PINCONF functions are not
supported
