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.
