[PATCH v2 08/11] iommu/arm-smmu-v3: Allocate IOPF queue for ARM_SMMU_FEAT_PRI

[Nicolin Chen]

arm_smmu_init_queues() allocates smmu->evtq.iopf only when FEAT_SVA and
ARM_SMMU_FEAT_STALLS are both advertised. A subsequent change will add PRI
support on top of the IOPF infrastructure, so the IOPF workqueue must also
exist on SMMUs supporting FEAT_PRI without FEAT_STALLS. Extend the
allocation condition to include FEAT_PRI.
