As per kernel commit 0672d22a1924 ("ARM: dts: imx: Fix the AR803X phy-mode) the correct phy-mode should be "rgmii-id", so fix it accordingly to fix the Ethernet regression.

This problem has been exposed by commit:

commit 13114f38e2ccea9386726d8b9831dfc310589548 Author: Vladimir Oltean vladimir.oltean@nxp.com Date: Thu May 7 00:11:51 2020 +0200

phy: atheros: Explicitly disable RGMII delays

To eliminate any doubts about the out-of-reset value of the PHY, that the driver previously relied on.

If bisecting shows that this commit breaks your board you probably have a wrong PHY interface mode. You probably want the PHY_INTERFACE_MODE_RGMII_RXID or PHY_INTERFACE_MODE_RGMII_ID mode.
