The Ethernet PHY on the Bananapi M64 has the RX and TX delays
enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins.

Fix the phy-mode description to correct reflect this so that the
implementation doesn't reconfigure the delays incorrectly. This
happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e
rx/tx delay config").

Fixes: e7295499903d ("arm64: allwinner: bananapi-m64: Enable dwmac-sun8i")
Fixes: 94f442886711 ("arm64: dts: allwinner: A64: Restore EMAC changes")
