drm/amd/display: Introduce KUnit to DML
KUnit unifies the test structure and provides helper tools that simplify the development. Basic use case allows running tests as regular processes, which makes easier to run unit tests on a development machine and to integrate the tests in a CI system.
For example, to execute all DRM unit tests: ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/gpu/drm/amd/display/amdgpu_dm/tests (the tool also allows using QEMU instead of UML by adding e.g. --arch=x86_64)
