[PATCH 6.6 014/156] arm64: dts: allwinner: h616: update emac for Orange Pi Zero 3

[Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>]

6.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chukun Pan <amadeus@xxxxxxxxxx>

[ Upstream commit b9622937d95809ef89904583191571a9fa326402 ]

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.
