The Ethernet PHY on the Cubieboard 4 and A80 Optimus have 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: 98048143b7f8 ("ARM: dts: sun9i: cubieboard4: Enable GMAC")
Fixes: bc9bd03a44f9 ("ARM: dts: sun9i: a80-optimus: Enable GMAC")
