I wonder if now that this header was moved outside of the tests directory,
if we should add stub functions in the header file that are just defined
but do nothing if CONFIG_DRM_KUNIT_TEST isn't enabled. So that including
it in drivers will be a no-op.

Or do you plan to conditionally include this header file in drivers? So
that is only included when CONFIG_DRM_KUNIT_TEST is enabled?

Another thing that wondered is if we want a different namespace for this
header, i.e: <drm/testing/drm_kunit_helpers.h>, to make it clear that is
not part of the DRM API but just for testing helpers.

But these are open questions really, and they can be done as follow-up:
