LoongArch: Fix GMAC's phy-mode definitions in dts
The GMAC of Loongson chips cannot insert the correct 1.5-2ns delay. So we need the PHY to insert internal delays for both transmit and receive data lines from/to the PHY device. Fix this by changing the "phy-mode" from "rgmii" to "rgmii-id" in dts. Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
