[U-Boot] sunxi: USB gadget does not work on H2+ after 92a30692b2b18f45aae6fdaae38d67ed03dd2d11

[Nuno Gonçalves]

This test is on 2018.09-rc2 with UMS enabled.

With your patch, I get this dmesg on the host:

[20121.718226] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad?
[20122.578151] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad?
[20122.578320] usb 1-4-port4: attempt power cycle
[20123.750104] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad?
[20124.602034] usb 1-4-port4: Cannot enable. Maybe the USB cable is bad?
[20124.602190] usb 1-4-port4: unable to enumerate USB device

u-boot console is the same, including loading the gadget:

Allwinner mUSB OTG (Peripheral)

If you tell me how you tested USB Gadget to work, I will reproduce your
test locally to confirm the issue.

Thanks,
Nuno
