odroid xu3/xu4: add bootclone and ubootupgrade environment scripts

Script ubootupgrade:
This script allows updating U-Boot from file u-boot-mmc.bin
existing on boot partition, e.g. with SD card reader.

This is useful for XU4, when U-Boot upgrade is needed,
then it can be delivered with 'boot.img' as regular file
and upgraded by running:
run ubootupgrade

Script bootclone:
This script allows cloning bootloader firmware including:
- bl1, bl2, U-Boot ,and TZSW
from bootable SD card to clean eMMC card using XU3/XU4 board.

This is useful, when user have SD card reader only and wants prepare
a bootable eMMC card.

The script expects that SD is bootable and can be run as follows:
run bootclone
