I think I'm on the right path :)
- Included SUNXI_SETUP_REGULATORS=0 to the bl31 make
- Changed the phy mode on arch/arm/dts/sun50i-h6-orangepi-one-plus.dts From rgmii-id to rgmii
This does not look like the correct fix. Please see this commit from Linux: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v...

What about using the Realtek PHY driver instead of the Generic one?

It's interesting that it keeps using Generic PHY.

OH! I believe I discovered something I overlooked:
On arch/arm/dts/sun50i-h6-orangepi-one-plus.dts:
reg_gmac_3v3: gmac-3v3 { compatible = "regulator-fixed"; regulator-name = "vcc-gmac-3v3"; regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; startup-delay-us = <100000>; enable-active-high; gpio = <&pio 3 6 GPIO_ACTIVE_HIGH>; /* PD6 */ vin-supply = <®_aldo2>; };After I connected GPIO 3 to GPIO 6, the Ethernet LED turned on!
Okay, I completely misunderstood this... and I lost the combination that turned the LED on :(
It seems that PD6 is not exposed on the GPIO header [1]. It is defined on the FBGA on the pin map session of the datasheet [2]. So, I don't believe I need to short the pins to get it working, but somehow it at least powered on the Ethernet port. I wish I remember the combination.

[2] https://linux-sunxi.org/images/5/5c/Allwinner_H6_V200_Datasheet_V1.1.pdf
UPDATE: I did it!
On u-boot shell:
gpio set pd6
then dhcp command works :). However, it doesn't get an IP and with static IP pinging doesn't work.
It seems to be able to send BOOTP broadcasts but it doesn't get an IP...
Combination was:
u-boot config: CONFIG_SPL_SPI_SUNXI=y CONFIG_SUN8I_EMAC=y
tfa config:
SUNXI_SETUP_REGULATORS=1 (or just unset this)
I still see:
=> dhcp sun8i_emac_eth_start: Timeout
And
Net: PHY reset timed out eth0: ethernet@5020000
