From: Maarten Lankhorst <maarten.lankhorst@xxxxxxxxxxxxxxx>
intel_crtc->config will be removed eventually, so use crtc->hwmode.
drm_atomic_helper_update_legacy_modeset_state updates hwmode,
but crtc->active will eventually be gone too. Set dotclock to zero
to indicate the crtc is inactive.
Changes since v1:
- With the hwmode update in drm*update_legacy_modeset_state removed,
intel_modeset_update_state has to assign it instead.
