So, I've solved the problem via adding a task:

do_create_fitimage() {
        cp ${THISDIR}/linux-yocto-custom/kernel-fit.its ${DEPLOY_DIR_IMAGE}
        uboot-mkimage -f ${DEPLOY_DIR_IMAGE}/kernel-fit.its
${DEPLOY_DIR_IMAGE}/kernel-fit.itb
}

addtask create_fitimage before do_packagedata after do_deploy

No the question is, how to handle out-of-tree DTS files?
meta/recipes-kernel/linux/linux-dtb.inc won't copy DTS files to
"${B}/arch/${ARCH}/boot/dts/${DTB}"
