Add properties in the DTSI file which is required for S-BOOT when used an external device tree when booting into U-Boot. S-BOOT is Samsung's proprietary bootloader, which chainloads U-Boot.
Since this device has multiple bank nodes, add memory nodes for each RAM bank. This is the format S-BOOT recognizes, and (re)populates it with the correct bank sizes.
