Mediatek SMI have two generations of HW architecture, here is the list
which generation the SoCs use:
generation 1: mt2701 and mt7623.
generation 2: mt2712, mt8173 and mt8183.
generation 2: mt2712, mt6779, mt8173 and mt8183.
There's slight differences between the two SMI, for generation 2, the
register which control the iommu port is at each larb's register base. But
