iommu/mediatek: add support for mtk iommu generation one HW
Mediatek SoC's M4U has two generations of HW architcture. Generation one uses flat, one layer pagetable, and was shipped with ARM architecture, it only supports 4K size page mapping. MT2701 SoC uses this generation one m4u HW. Generation two uses the ARM short-descriptor translation table format for address translation, and was shipped with ARM64 architecture, MT8173 uses this generation two m4u HW. All the two generation iommu HW only have one iommu domain, and all its iommu clients share the same iova address. These two generation m4u HW have slit different register groups and register offset, but most register names are the same. This patch add iommu support for mediatek SoC mt2701.
