imx: hab: Enable hab.c to authenticate additional images in open configuration

Currently it's not possible to authenticate additional boot images in HAB
open configuration.

The hab.c code is checking if the SEC_CONFIG[1] fuse is programmed prior
to calling the hab_authenticate_image() API function. Users cannot check
if their additional boot images has been correctly signed prior to closing
their device.

Enable hab.c to authenticate additional boot images in open mode so HAB
events can be retrieved through get_hab_status() function.
