2023-07-31drm/vc4: tests: mock: Use a kunit action to unregister DRM deviceMaxime Ripard
The *_mock_device functions allocate a DRM device that needs to be released using drm_dev_unregister. Now that we have a kunit release action API, we can switch to it and don't require any kind of garbage collection from the caller.

In order to test the current atomic_check hooks we need to have a DRM device that has roughly the same capabilities and layout that the actual hardware. We'll also need a bunch of functions to create arbitrary atomic states. Let's create some helpers to create a device that behaves like the real one, and some helpers to maintain the atomic state we want to check.
