Boot: Enable multi-image boot
This patch adds the capability to handle multiple firmware images,
to update them independently. Also update the design documentation.
It separates the completion of aborted image swap operations and the
update of images even more as these should be happening at different
stages of the boot process according to the design proposal of
the multiple image support:
