ARM: mvebu: Enable NAND controller in ReadyNAS 2120 .dts file

Now that NAND controller support is available for Armada XP
(cb28e2537a6f: ARM: mvebu: Add support for NAND controller in
Armada 370/XP), this patch enables support for ReadyNAS 2120
and defines default partition layout as delivered by NETGEAR.

As described in similar commits 2be2bc39c6f0 (ARM: mvebu: Enable
NAND controller in Armada XP GP board) and d8c552dddfbf (ARM:
mvebu: Enable NAND controller in Armada 370 Mirabox),
"marvell,keep-config" parameter is used as current support does
not allow for setting of timing parameters yet.
