ARM: dts: am57xx: fix networking on boards with ksz9031 phy
Since commit bcf3440c6dd7 ("net: phy: micrel: add phy-mode support for the KSZ9031 PHY") the networking is broken on boards: am571x-idk am572x-idk am574x-idk am57xx-beagle-x15 All above boards have phy-mode = "rgmii" and this is worked before because KSZ9031 PHY started with default RGMII internal delays configuration (TX off, RX on 1.2 ns) and MAC provided TX delay. After above commit, the KSZ9031 PHY starts handling phy mode properly and disables RX delay, as result networking is become broken. Fix it by switching to phy-mode = "rgmii-rxid" to reflect previous behavior.
