I don't think anyone using the *config tools will ever see this text, as
there's no prompt. So you might as well make this a comment or drop it
altogether.

Is this selected by more than just MTK_IOMMU (see 2/5)? If not, I think
MTK_SMI will be set and unset in lockstep with MTK_IOMMU. In other
words, you could as well use one Kconfig symbol.

Thanks,
