While the smi-common configuration is specific to this SoC, on the LARB side, this is similar to MT8173, in the sense that it doesn't need the port in LARB, and the register layout is also compatible with that one, which makes us able to fully reuse the smi-larb platform data struct that was introduced for MT8173.
