On a CC6, the 'env default -a' command deletes the 'soc_family' variable
that is used on the U-Boot boot scripts to configure the name of the
device tree file to load.
Then if we try to boot into recovery directly (without a reset) because
the variable is not available, it fails to compose the correct name for
the fdt, and gives the error:
reading uImage--ccimx6sbc-id129.dtb
** Unable to read file uImage--ccimx6sbc-id129.dtb **
Force a reset, so the 'soc_family' variable is available again and the
correct fdt_file is loaded.
While on it, add some blank lines to the 'recovery reboot' message, so
it's easier to read.

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.
