amd_iommu: Toggle memory regions based on address translation mode
Enable the appropriate memory region for an address space depending on the
address translation mode selected for it. This is currently based on a
generic x86 IOMMU property, and only done during the address space
initialization. Extract the code into a helper and toggle the regions based
on whether the specific address space is using address translation (via the
newly introduced addr_translation field). Later, region activation will also
be controlled by availability of DMA remapping capability (via dma-remap
property to be introduced in follow up changes).
