ARM: dts: exynos7870-on7xelte: add properties to make S-BOOT happy

Browse Source 
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.
