drm/tegra: Let core take care of normalizing the zpos

Browse source 
Set the drm_mode_config->normalize_zpos and call the generic
drm_atomic_helper_check() instead of duplicating it within
tegra_atomic_check().

Call tegra_display_hub_atomic_check() after the drm_atomic_helpre_check()
returned without error.
