of: remove unused and misleading #cells in /memreserve
barebox creates a /memreserve node to hold FDT reservation entries
inside its reg property for unflattened device trees that are copied
back into the FDT reservation table on flattening.
These reservation entries are pairs of big-endian 64-bit start+size
pairs. To properly describe these in DT, we would need the
(#address|#size)-cells properties at the root node, not in the same node
having the reg property. As we don't read back these properties anyway,
just drop them.
No functional change.
