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.
