iommu/riscv: Add RISC-V IOMMU platform device driver
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.
