Colibri-T20 can come in 256 MB RAM (with 512 MB NAND) or 512 MB RAM (with 1024 MB NAND) flavors. Both of them will use the same DTSI expecting the bootloader to do the fixup of /memory node. However in case it does not happen, let's stay on safe side by limiting the memory to 256 MB for both versions of Colibri-T20. Rename to remove the unnecessary memory size from the device tree file name. While at it, also follow the typical Toradex SoC, module, carrier board hierarchy.
