Having the functional unit names in each bank decode is only misleading as this code supports multiple families and there's no guarantee the mapping between FUs and MCE banks will stay the same. And also, knowing the functional unit name doesn't help much since you end up looking at the respective BKDG anyway. So drop all FU references and use the MC bank numbers instead.
