drm/vc4: tests: Introduce a mocking infrastructure
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.
