This removes a bogus empty "ranges" property in the EBC device node
of the Bamboo board device-tree.
The "ranges" property should be created by the wrapper code when it is
implemented.  Until then, remove the empty property since it incorrectly
implies that there is a 1:1 address mapping between the EBC and the OPB.
This also fixes a warning from newer DTCs.
