This is close but its still not 100% right. If you put the files into
${DEPLOYDIR} (such as ${DEPLOYDIR}/${DTB_NAME}.dtb), the sstate code
itself will ensure it makes it to ${DEPLOY_DIR_IMAGE}/${DTB_NAME}.dtb.
You can therefore remove the last bit of duplication in this function,
don't touch ${DEPLOY_DIR_IMAGE} at all and the files will still appear
there, just like kernel_do_deploy() itself does.

Cheers,

Richard
