Right now callers of drm_crtc_commit need to check whether the interface is legacy or atomic before passing the TEST_ONLY flag. Additionally, the fallbacks for legacy are in-place in the common code. Add a test_only arg to the crtc_commit hook. This way, there's no risk to pass atomic-only flags to the legacy function (add an assert to ensure this) and all of the legacy-specific logic can be put back into legacy.c (done in next commit).
