The property should probably have a DT binding, and be named "linux,atags".

It may also help to check if the "linux,atags" property already exists and not
create it otherwise. That way we can put it into the n900 dts file and have
it updated by the compat code, but not expose the atags on other platforms
unless they opt in.
