arm64: dts: allwinner: h616: update emac for Orange Pi Zero 3

[ 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.
