Using non-DT becomes so rare that my knowledge about it gets rusty :(

Yes, one can't mix i2c_add_numbered_adapter and i2c_add_adapter well,
and this is even documented. However, since you are DT only, this
doesn't apply.

I don't know all of your dts files, but I assume there is already an
alias for busses 0/2 somewhere?
