Embed the u-boot flash image size at a known offset from the start of u-boot so that SPL can use it while loading u-boot from a non-XIP media.

0xdeadbeef does not seem like a good magic value to identify this header format -- especially since it looks like that may have been the value present in the older images that don't have this header (depending on whether the .balignl needed to pad).
Thanks for pointing this out. I will change it to something different.
