The current implementation of images does not cover all the requirements of the current, updated UPL spec. Add support for an entry address, the offset of the image within the FIT as well as the load address and size, which are subsumed into the new 'reg' property.
Support writing this information out to the UPL handoff.
Update SPL to handle the struct change as well.
