iommu/mediatek: Convert M4Uv1 to iommu_fwspec
Our per-device data consists of the M4U instance and firmware-provided list of LARB IDs, which is a perfect fit for the generic iommu_fwspec machinery. Use that directly instead of the custom archdata code - while we can't rely on the of_xlate() mechanism to initialise things until the 32-bit ARM DMA code learns about groups and default domains, it still results in a reasonable simplification overall.
