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

Instead of re-implementing the drm_atomic_helper_check() locally with just
adding drm_atomic_normalize_zpos() into it, set the
drm_mode_config->normalize_zpos.

Note: the drm_atomic_helper_check() now includes

if (state->legacy_cursor_update)
state->async_update = !drm_atomic_helper_async_check(drm, state);

which was added after the driver moved away from using it
(38d868e41c4b9250d5a115c049dc2d48f4909581 drm: Don't force all planes to
be added to the state due to zpos)
