Ah, yes. I had not thought about that. A device at address 0 would be
found, but a device at address 16 would be missed.

Please add this compatible string to Documentation/devicetree/bindings/net/dsa/marvell.txt

It looks like you could refactor mv88e6352_g1_reset() to call
this function, and then mv88e6352_g1_wait_ppu_polling(chip);

Otherwise, this looks good.
