Reviewers please for Flat Image Tree (FIT) Spec

[Simon Glass]

Hi,

This spec <https://fitspec.osfw.foundation/> is undergoing another round of
changes, but since it is now hosted outside U-Boot there are not too many
people seeing the PRs.

If you have an interest in FIT, please can you take a look at the PRs
<https://github.com/open-source-firmware/flat-image-tree/pulls> and ideally
send me your github handle so I can add you to the project as a reviewer.

Thanks,
Simon
