Russell King's commit de696c63c1dc ("net: stmmac: socfpga: convert to
use phy_interface") replaced mac_interface with phy_interface in
socfpga_get_plat_phymode(), noting that no upstream DTS files set the
"mac-mode" property, making the two values identical.

The Agilex5 SoCDK TSN Config2 board is an exception: its gmac1 TSN
port uses GMII internally in the MAC while the PHY-side interface is
RGMII, so mac-mode and phy-mode differ.

Maybe you need to represent the hardware block which magically
converts GMII to RGMII in DT?
