To split the patches I would have to do:
1. Add USXGMII support to Aquantia PHY driver
2. DTS changes
3. Don't accept XGMII any longer in Aquantia PHY driver
This seemed to me to be too much overhead considering the very small
change.

Just making the DTS changes a separate patch would break bisecting.
