Partially revert "drm/i915: Use full atomic modeset."
This partially reverts commit 74c090b1bdc57b1c9f1361908cca5a3d8a80fb08. The DRIVER_ATOMIC cap cannot yet be exported because i915 lacks async support. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
