[U-Boot] [PATCH 8/8] arm: dts: k3-am654-base-board-u-boot: change cpsw2g interface mode to rgmii-rxid

The AM654 SoC doesn't allow to disabling RGMII TX internal delay in CPSW2G
MAC. Hence, change CPSW2G interface mode to "rgmii-rxid" - RGMII with
internal RX delay provided by the PHY, the MAC will add an TX delay in this
case.
