[PATCH v3 10/13] iommu/arm-smmu-v3: Allocate IOPF queue for ARM_SMMU_FEAT_PRI

[Nicolin Chen]

After the previous change drops the FEAT_SVA gate, arm_smmu_init_queues()
allocates smmu->evtq.iopf when the SMMU advertises FEAT_STALLS. PRI support
is being added on top of the IOPF infrastructure, so extend the allocation
condition to cover SMMUs that advertise FEAT_PRI without FEAT_STALLS.
