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.
