Subject: [PATCH 04/10] ARM: dts: sun7i: bananapi-m1-plus: Enable RGMII RX/TX delay on Ethernet PHY

From: Chen-Yu Tsai <wens@...e.org>

The Ethernet PHY on the Bananapi M1+ 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: 04c85ecad32a ("ARM: dts: sun7i: Add dts file for Bananapi M1 Plus board")
