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

Add mt8195 smi supporting in the bindings. In mt8195, there are two smi-common HW, one is for vdo(video output), the other is for vpp(video processing pipe). They connect with different smi-larbs, then some setting(bus_sel) is different. Differentiate them with the compatible string.
