ARM: imx: Update Fast ethernet PHY MDIO addresses to match DH i.MX8MP DHCOM rev.200

The production DH i.MX8MP DHCOM SoM rev.200 uses updated PHY MDIO addresses
for the Fast ethernet PHYs. Update the base SoM DT and SoM rev.100 backward
compatibility DTO to cater for this change.

Since the MDIO address adjustment is now also in the rev.100 SoM DTO, not
only in the rev.100 PDK3 DTO, update Makefile accordingly as well, else the
DTC would complain about the DTO overriding the 'reg' property without also
updating the node unit-address, which is not doable without duplicating the
entire PHY node in the DTO, which leads to large amount of duplication with
no gain.
