tools/kwboot: Sync with latest barebox version to support Armada XP
The barebox version of the kwboot tool has evolved a bit. To support Armada XP and Dove. Additionally a few minor fixes have been applied. So lets sync with the latest barebox version. Please note that the main difference between both versions now is, that the U-Boot version still supports the -p option, to dynamically patch an image for UART boot mode. I didn't test it now though.
