Changes since v1:
 - remove 'pinctrl-' prefix for pinctrl sub-nodes
 - separate config and mux nodes

Changes since RFC v2:
 - add pinconf properties to zc702 mdio node
 - remove arguments from bias-related props

Changes since RFC v1:
 - separate DT changes into their own patch

On linux-next the equivalent no longer works for the Parallella, with
gpio failing to probe.

If I move these two properties to the leds node (for which I am
configuring gpio 7) then I get a heartbeat as before.
