I realise you're just moving this node, but I'm surprised it hasn't
caused trouble otherwise. This happens to work due to a quirk of I2C
device IDs in the kernel but it's not a documented compatible.
Compatible strings need to represent the physical device. Can you
please split out a patch either dropping this node, or replacing the
compatible string with something appropriate?
