Ideally auto negotiation must work, but :-(
I don't think this is not for SoC/PHY erratum since both are working okay with other boards.
Only the difference is on RD6281A the multichip mode is used,
I am discovering why it is not working.

Meanwhile this patch does not harm anything, it enables RD6281A usecase
We can undo it latter if I could positively discover the fix ;-D
