ACPI/IORT: Add support for ARM SMMU platform devices creation
In ARM ACPI systems, IOMMU components are specified through static IORT table entries. In order to create platform devices for the corresponding ARM SMMU components, IORT kernel code should be made able to parse IORT table entries and create platform devices dynamically. This patch adds the generic IORT infrastructure required to create platform devices for ARM SMMUs. ARM SMMU versions have different resources requirement therefore this patch also introduces an IORT specific structure (ie iort_iommu_config) that contains hooks (to be defined when the corresponding ARM SMMU driver support is added to the kernel) to be used to define the platform devices names, init the IOMMUs, count their resources and finally initialize them.
