[POWERPC] Add device tree for Ebony
Add a device tree for the Ebony evaluation board (440GP based). This tree is not complete or finalized. This tree needs a version of dtc recent enough to include reference-to-labels to process. Signed-off-by: David Gibson <dwg@au1.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
