Revert "iommu/arm-smmu-v3: Disable detection of ATS and PRI"
This reverts commit b5e86196b83fd68e065a7c811ab8925fb0dc3893.
Now that ATC invalidation is performed in the correct places and without
incurring a locking overhead for non-ATS systems, we can re-enable the
corresponding SMMU feature detection.
