mkimage will now report information about loadable
Added FIT_LOADABLE_PROP, so the user can identify an optional entry named "loadables" in their .its configuration. "loadables" is a comma separated list in the .its Documentation can be found in doc/uImage.FIT/source_file_format.txt and doc/uImage.Fit/multi-with-loadables.its Signed-off-by: Karl Apsite <Karl.Apsite@dornerworks.com> Reviewed-by: Simon Glass <sjg@chromium.org>

The FDT blob is required to properly boot FDT based kernel, so the minimal
configuration for 2.6 FDT kernel is (kernel, fdt) pair.
