[PATCH 3/5] ARM: dts: at91: sama5d2: Add memory node in devicetree

sama5d2 support from DRAM will be modified to use device tree instead of
hardcoded addresses. In order to prepare that, add the memory node to
sama5d2.dtsi file since the boards supported by U-Boot with sama5d2 all
contains 512Mb of DDR.
