Introduce platform device driver for implementation of RISC-V IOMMU architected hardware. Hardware interface definition located in file iommu-bits.h is based on ratified RISC-V IOMMU Architecture Specification version 1.0.0. This patch implements platform device initialization, early check and configuration of the IOMMU interfaces and enables global pass-through address translation mode (iommu_mode == BARE), without registering hardware instance in the IOMMU subsystem.
