Subject: [PATCH 1/2] ARM: dts: uniphier: Change phy-mode to RGMII-ID to enable delay pins for RTL8211E

After applying the commit bbc4d71d6354
("net: phy: realtek: fix rtl8211e rx/tx delay config"), the configuration
register for TXDLY and RXDLY is set correctly.

Although PXs2 boards have RTL8211E for gigabit network PHY, it turrned out
that the phy-mode should be RGMII-ID mode. This changes 'phy-mode' property
to 'rgmii-id' as default.
