ccimx6ulsbc: add U-Boot scripts for deploying and booting the system 

- boot.txt
    Sets the device tree filename basing on the SOM variant read from
    the HWID and boots from NAND.
- install_linux_fw_sd
    Deploys a full system (as generated by Digi Embedded Yocto) from
    a FAT formatted micro SD card into the NAND flash.
