setup-disk: Add preliminary support for u-boot based boards
Currently, this bootloader is not set automatically and needs to be set
manually using the BOOTLOADER environment variable, e.g.:
BOOTLOADER=u-boot setup-disk -m sys /dev/sda
Furthermore, it relies on the update-u-boot script to install the
bootloader based on the automatically determined defaults.
