In theory it could still be used on SH-Mobile AG5 and R-Mobile A1 SoCs, but that requires adding DT support to the driver, which is not planned. Remove the driver, it can be resurrected from git history when needed.

This will do the bulk of the heavy lifting for IOMMU-backed dma-mapping. Since associating an IOVA allocator with an IOMMU domain is a fairly common need, rather than introduce yet another private structure just to do this for ourselves, extend the top-level struct iommu_domain with the notion. A simple opaque cookie allows reuse by other IOMMU API users with their various different incompatible allocator types.

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.
