NAND partitions may have pre-existing UBI volume information
and that will tell U-Boot to use 'ubiwrite' to keep UBI wear
leveling information instead of erasing the NAND partition
beforehand. Given that the UBI support in U-Boot is not
particularly complete and stable, and specially if the NAND
partition table has been changed, this could result into
problems during the UBI volume initialization or during the
update process. To prevent such problems it is better that
the NAND partitions are erased.
This loses the UBI wear leveling information but provides
a more reliable deployment install script.

A corner case requires to save the environment so that the
boot command works after reset.

- 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.
The u-boot-dey recipe is now fully shared by ccimx6 and ccimx6ul platforms
so we can remove the platform-specific appends.
