Subject: ARM: dts: uniphier: Change phy-mode to RGMII-ID to enable delay pins
 for RTL8211E
Git-commit: 9ba585cc5b56ea14a453ba6be9bdb984ed33471a
Patch-mainline: v5.13-rc1
References: git-fixes

UniPhier PXs2 boards have RTL8211E ethernet phy, and the phy have the RX/TX
delays of RGMII interface using pull-ups on the RXDLY and TXDLY pins.

After the commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx
delay config"), the delays are working correctly, however, "rgmii" means
no delay and the phy doesn't work. So need to set the phy-mode to
"rgmii-id" to show that RX/TX delays are enabled.
