arm64: dts: uniphier: Change phy-mode to RGMII-ID to enable delay pins for RTL8211E

Browse Source 
[ Upstream commit dcabb06bf127b3e0d3fbc94a2b65dd56c2725851 ]

UniPhier LD20 and PXs3 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 bbc4d71d63 ("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.
