Enable Ethernet on Orange Pi One Plus by using the correct phy for Realtek RTL8211E instead of the Generic One. Also use CONFIG_MACPWR to turn on ethernet on startup.
After this patch is applied, a few issues can be seen:
there's still a PHY reset timed out error that doesn't seem to cause any impacts to the overall connection
sometimes the emac driver times out after reset (yellow LED turns on and never blinks)
For future patches: for now, CONFIG_MACPWR is the only way to enable Ethernet on boot. There's already code on the dts for using the 3v3-gmac regulator. However, it is not probed on boot, so it only starts after a "regulator status" command is issued.
More details about the troubleshooting on [1].
