Since DTB belongs to the kernel and should stay with it, how about
moving both kernel and DTB deployment together into a separate recipe,
rather than keeping them in the image generation process? Logically,
the deployment of these artifacts does not belong to the image
generation process. With this approach, kernel and DTB are only
deployed once, DTB names remain the same. We do have one API change
here, kernel image names are no longer prefixed with the image name.
