iommu/arm-smmu: Add initial driver support for ARM SMMUv3 devices
Version three of the ARM SMMU architecture introduces significant changes and improvements over previous versions of the specification, necessitating a new driver in the Linux kernel. The main change to the programming interface is that the majority of the configuration data has been moved from MMIO registers to in-memory data structures, with communication between the CPU and the SMMU being mediated via in-memory circular queues. This patch adds an initial driver for SMMUv3 to Linux. We currently support pinned stage-1 (DMA) and stage-2 (KVM VFIO) mappings using the generic IO-pgtable code.
