add u-boot ethernet support to orange pi one plus (h6)

Browse Source 
This patch adds ethernet support to orange pi one plus. The patch has
been submitted to the mailing list and is being added to the bbappend
for u-boot.

Unfortunately, is doesn't keep ethernet on after kernel boot, as the
kernel dts needs to be synced with the u-boot dts.

Submitted patch waiting for approval on the upstream: https://lore.kernel.org/u-boot/30debca8b31ed4d2cbd64850d48b81ac@posteo.net/T/#t

Subject: [PATCH] sunxi: H6: Enable Ethernet on Orange Pi One Plus
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].
