drm/tegra: Atomic conversion, phase 1

Implement initial atomic state handling. Hook up the CRTCs, planes' and connectors' ->atomic_destroy_state() callback to ensure that the atomic state objects don't leak. Furthermore the CRTC now implements the ->mode_set_nofb() callback that is used by new helpers to implement ->mode_set() and ->mode_set_base(). These new helpers also make use of the new plane helper functions which the driver now provides. Signed-off-by: Thierry Reding <treding@nvidia.com>
