Josua Mayer 88389bfe41 mvebu: update boot-script to use generic variables
U-Boot provides standard variables for load addresses, and
filesystem-agnostic load-commands. Furthermore thanks to distro-boot,
the device and partition from which the system boots is known.
The new boot-script makes use of all this information.

Tested on the only board that uses this boot-script: Clearfog Pro

# Standard Boot-Script
# use only well-known variable names provided by U-Boot Distro boot
# This script assumes that there is a boot partition,
# and that the root partition is always the next one.
# Override DeviceTree for Clearfog Base
# removed once U-Boot is able to detect the board variant.
