The production DH i.MX8MP DHCOM SoM rev.200 uses updated PHY MDIO addresses for the Fast ethernet PHYs. Update the base SoM DT to cater for this change. Prototype rev.100 SoM was never publicly available and was manufactured in limited series, anything currently available is rev.200 or newer, so it is safe to update the DT this way.
