[PATCH 15/17 v1] ARM: ixp4xx: Add DT bindings

[Linus Walleij <linus.walleij@linaro.org>]

This adds initial device tree bindings for the IXP4xx machines.
This time I tried something wild and crazy and try to make proper
JSON-style YAML bindings for the top level.

Cc: devicetree@vger.kernel.org

I have no clear idea on how to auto-test this schema for validity,
since it is a bit of a new thing I hope to figure it out as
we go.
