Merge patch series "mkimage: validate image references in FIT configurations"

Aristo Chen <jj251510319013@gmail.com> says:

This series introduces a validation step in mkimage to ensure that all image
names referenced under the /configurations node of a FIT source (ITS) are
actually defined under the /images node.

### Motivation

When using mkimage to build FIT images, it's easy to mistakenly reference
nonexistent image nodes in configurations (e.g., referencing a missing `fdt` or
`firmware` node). Such issues are often not caught until runtime in U-Boot.

This series aims to catch these errors early during FIT image creation by
validating the configuration references in mkimage itself.
