[PATCH v2 4/4] arm64: allwinner: a64: disable the RTL8211E internal RX delay on Pine64+
Some Pine64+ boards have a broken RTL8211E PHY, which cannot work reliably in 1000Base-T mode with default configuration. A solution is passed to Pine64, which is said to be disabling the internal RX delay of the PHY. Enable the hack by set the PHY mode to RGMII-TXID.
