Error writing files: failed to resolve mod `tests`: <opentitan dir>/sw/device/silicon_owner/tock/kernel/src/tests.rs does not exist

The described file indeed does not exist. If it's supposed to be autogenerated by something A) it's discouraged to put generated files next to non-generated files for reasons like this and B) it should be a (transitive) dependency of the rustfmt_fix rule.

That file is not supposed to exist; that code was copied out of another repository (Tock) but the tests were not copied over as they are not compatible with our test infrastructure. We don't expect it to compile with --cfg test.

It looks like there is significant divergence between rustfmt_check and rustfmt_fix. In addition to the above error, rustfmt_fix currently makes changes to files even when rustfmt_check passes (tested on both master and earlgrey_es_sival).

This is a known issue, I have pending PRs that fix the rustfmt_check and also can take care of this issue with the module but this is low priority: https://github.com/lowRISC/rules_rust/pull/5 and https://github.com/lowRISC/opentitan/pull/21631

with this in mind I'm going to upload a PR removing the test reference from main.rs
