ci: 'MIT' license verification fail on permissive license

[b0661]

Describe the bug

PR #10885 contains files that are licensed "mit" ( see https://spdx.org/licenses/MIT.html). This is a much more permissive license than apache-2.0. It should not make CI fail.

To Reproduce

Add a file wirh "SPDX-License-Identifier: mit" and run CI.

Expected behavior

CI license verification shall pass on "SPDX-License-Identifier: mit".

Impact

CI of PR #10885, #10888 declared failed.

Screenshots or console output

Environment (please complete the following information):

Zephyr CI

Additional context

[nashif]

Any file going into the zephyr tree with a different license that the project license needs to be reviewed. This check in CI is currently not 'required' for merging and still under heavy development, so a maintainer can override this check after reviewing the warnings and determining that the files are ok.

Will add some text explaining the above in the comment posted by CI.

[b0661]

Reviewers usually do not review until the CI status is "passed".

Can this become a hint for reviewers and CI set to "passed"?

[nashif]

We now add more information about the license scan, any license warning need to be reviewed and processed by someone, making them PASS is just going to be misleading. Those who merge can always override the check. My concern is that if we make it PASS, nobody will look at the warnings of non APL licensed files we are pulling into the tree.
