[PATCH v3 11/14] doc: mkimage: Remove AUTHORS section

[Sean Anderson]

Per man-pages(7), "use of an AUTHORS section is strongly discouraged."
Remove it, and instead add some copyright notices and an SPDX. The default
license for U-Boot is GPL2, so that's what I put. The copyright dates are
based on the commit dates.
