Add Kconfig entry: CONFIG_DTB_FILE to be able to provide the path to DTB we want to embed into Xen image. If no path provided - the dtb will not be embedded. Remove the line: AFLAGS-y +=3D -DCONFIG_DTB_FILE=3D\"$(CONFIG_DTB_FILE)\" as it is not needed since Kconfig will define it in a header with all the other config options.
