Currently the type-1 IOMMU instantiation depends on "ARM_SMMU || ARM_SMMU_V3", while it applies to other ARM/ARM64 platforms with an IOMMU (e.g. Renesas VMSA-compatible IPMMUs). Instead of extending the list of IOMMU types on ARM platforms, replace the list by "ARM || ARM64", like other architectures do. The feature is still restricted to ARM/ARM64 platforms with an IOMMU by the dependency on IOMMU_API.
