Currently in order to link existing DTB into Xen image we need to either specify option CONFIG_DTB_FILE on the command line or manually add it into .config. Add Kconfig entries: CONFIG_LINK_DTB and CONFIG_DTB_FILE to be able to select this option and provide the path to DTB we want to embed into Xen image.
