fdt: Print an error when a device tree file is not supplied
Previously the build error was cryptic if CONFIG_OF_EMBED is defined but
CONFIG_DEFAULT_DEVICE_TREE is not. This corrects that, and also makes
sure that no device tree is compiled unless CONFIG_OF_EMBED is defined.
BUG=chromium-os:11623
TEST=build with and without each of CONFIG_DEFAULT_DEVICE_TREE, CONFIG_OF_EMBED
