As pointed out by Daniel Vetter, we should be usinng drm_drv_uses_atomic_modeset() for determining whether or not we want to make the debugfs nodes for atomic instead of checking DRIVER_ATOMIC, as the former isn't an accurate representation of whether or not the driver is actually using atomic modesetting internally (even though it might not be exposing atomic capabilities).
