[PATCH] sunxi: dts: arm64: update emac for Orange Pi Zero 3

[Andre Przywara]

From: Chukun Pan <amadeus at jmu.edu.cn>

The current emac setting is not suitable for Orange Pi Zero 3,
move it back to Orange Pi Zero 2 DT. Also update phy mode and
delay values for emac on Orange Pi Zero 3.
With these changes, Ethernet now looks stable.

Fixes: 95c3b0635ea4 ("sunxi: dts: arm64: update devicetree files from Linux-v6.6-rc6")

Hi,

this is a port of the corresponding Linux patch, that fixes Ethernet
on that board. The patch is in Linux' sunxi/fixes-for-6.7 queue,
awaiting a merge anytime soon.
For me this indeed fixes Ethernet operation in U-Boot on that board.

Cheers,
Andre
