core: dts: lx2160a: add memory region

With patch 8a6ca14 (core: arm: get DDR range from embedded DTB)
now DDR ranges are taken from Embedded DTB if enabled and will
ignore DDR ranges defined by register_ddr().
Since Dynamic shared memory and Embedded DTB config is enabled
on LX2160A platforms, need to add the DDR ranges to the DTS.
