The IOPF (I/O Page Fault) feature is now enabled independently from the SVA feature, because some IOPF implementations are device-specific and do not require IOMMU support for PCIe PRI or Arm SMMU stall. Enable IOPF unconditionally when enabling SVA for now. In the future, if a device driver implementing a uacce interface doesn't need IOPF support, it will need to tell the uacce module, for example with a new flag.
