Only two boards in the tree set the macro DWC_NET_PHYADDR. Both have CONFIG_DM_ETH_PHY=y, so should set the phy address in DT if necessary.
The imx8mp_evk does set the correct address in device tree. The other board seems to be a copy-paste-adapt from an old version of the imx8mp_evk config header, given the "#ifdef CONFIG_DWC_ETH_QOS" block that has been removed from imx8mp_evk header in commit 127fb454955. Its device tree doesn't even enable (i.e., set 'status = "okay"') the &eqos node. But the other ethernet device, &fec, does get enabled, and does have a phy sitting at address 4 (and it also has a corresponding legacy #define CONFIG_FEC_MXC_PHYADDR 4). So I believe it should be completely safe to remove it from there as well.
