[PATCH v2] arm64: dts: imx8mp: Update Fast ethernet PHY MDIO addresses to match DH i.MX8MP DHCOM rev.200

[Marek Vasut]

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.
