At this point the IOMMU support isn't used for SPL. While I can't rule out we'll see an SoC at some point the needs it, I don't think I've seen an SoC that has devices that are typically used in SPL (MMC, NOR flash, memory controllers) behind an IOMMU. So switching to IS_ENABLED(CONFIG_IOMMU) seems more logical to me.
