drm/tegra: dc: Simplify atomic plane helper functions
Remove the tegra_dc_disable_window() function whose only purpose was to allow tegra_plane_atomic_update() to also call it. Fix that by shuffling tegra_plano_atomic_disable() to before tegra_plane_atomic_update(). While at it, also remove the overlay plane helper functions because they are exactly the same as the primary plane helper functions. Signed-off-by: Thierry Reding <treding@nvidia.com>
