Subject: [PATCH 5.9 089/252] arm64: dts: allwinner: h5: libretech-all-h5-cc: Enable RGMII RX/TX delay on PHY

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

[ Upstream commit 2bd8570d20c88909b8be3251727a26476b02652c ]

The Ethernet PHY on the Libre Computer ALL-H5-CC 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").
