[PATCH AUTOSEL 6.9 31/44] LoongArch: Fix GMAC's phy-mode definitions in dts

[Sasha Levin <sashal@kernel.org>]

From: Huacai Chen <chenhuacai@loongson.cn>

[ Upstream commit eb36e520f4f1b690fd776f15cbac452f82ff7bfa ]

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.
