Since only HiSilicon platform has such erratum, and I think it works with
both old version of firmware, I'm fine with removing this erratum framework.
Yeah, seems a decent change on its own, even without the SMMU PMCG
driver changes.
But we still need to check on patch "[PATCH RFC 2/6] iommu/arm-smmu-v3:
Record IIDR in arm_smmu_device structure" to progress any of this.
Will, Robin, Any opinion on that patch?
