[PATCH 2/2] ARM: dts: at91: add devicetree for the Axentia Nattis with Natte power

[Peter Rosin <peda-koto5C5qi+TLoDKTGw+V6w@public.gmane.org>]

The Axentia Nattis is a device designed for presenting departures for
public transport systems. The Natte helper board provides power and
features a battery of battery chargers.
