iommu/arm: Add support for ARM Ltd. System MMU architecture

Browse Source 
This patch adds support for SMMUs implementing the ARM System MMU
architecture versions 1 or 2. Both arm and arm64 are supported, although
the v7s descriptor format is not used.

Support for implementations of the ARM System MMU architecture
versions 1 and 2. The driver supports both v7l and v8l table
formats with 4k and 64k page sizes.
Say Y here if your SoC includes an IOMMU device implementing
the ARM SMMU architecture.
