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.
