Some boards need to load an ELF file using the 'loadables' property, but the file has segments at different memory addresses. This means that it cannot be supplied as a flat binary. Allow generating a separate node in the FIT for each segment in the ELF, with a different load address for each. Also add checks that the fit,xxx directives are valid.
