mambo: Fix reserved-ranges node
The DT bindings for the /reserved-memory node requires that it:
a) Has #size-cells equal to the root
b) Has #address-cells equal to the root
c) Has an empty ranges property (i.e directly maps on the root)
Currently we do not assign any of these when generating the Mambo
device tree which causes the booted kernel to ignore the reservations
in the /reserved-memory node.
