All recent POWER systems, Power 8 and 9 specifically, support an IOMMU (it can't be disabled). The functionality of the IOMMU is different depending on whether it's running on a bare metal PowerNV system or in a virtual environment (PowerVM LPAR or KVM/QEMU). DPDK currently supports the IOMMU found on PowerNV platforms, sPAPRv2, so IOVA=VA mode can be enabled when the correct platform is detected. The POWER IOMMU type can't be detected through mechanisms such as parsing files in the /sys hierarchy like x86_64 systems so the /proc/cpuinfo file is parsed to determine whether Linux is running on bare metal (i.e. PowerNV) or in a virtual environment (KVM/QEMU).
