This adds a device tree node for the infrared receiver connected to a
GPIO pin on the Radxa Rock.

hmm, on second glance, I'm actually not sure if this shouldn't belong in the 
soc subnode, like the gpio-keys and leds.

(adding devicetree mailing list)

I placed the IR receiver under the root node after looking at what
other boards do, for example:

  imx6dl-hummingboard.dts
  imx6qdl-cubox-i.dtsi
  dove-cubox.dts

On the other hand, if gpio-keys and leds are under the soc node
probably it makes sense to follow the same rule also for the IR
receiver.
