[PATCH 3/3] sunxi: H616: Add OrangePi Zero 3 board support

[Mikhail Kalashnikov]

Hi Andre!
Thanks for your patches. I started checking and noticed that USB storage
was not working:

=> usb reset
resetting USB...
Bus usb at 5200000: USB EHCI 1.00
Bus usb at 5200400: USB OHCI 1.0
scanning bus usb at 5200000 for devices... 1 USB Device(s) found
scanning bus usb at 5200400 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 0 Storage Device(s) found
=> usb storage
No storage devices, perhaps not 'usb start'ed..?

Otherwise my OpiZero3 (4GB) board looks working.
Ethernet works with my 10 Mbps usb-dongle.

sf probe detect spi nor flash:
=> sf probe
SF: Detected zb25vq128 with page size 256 Bytes, erase size 4 KiB, total 
16 MiB

Loading the kernel and running the operating system (from microsd) also
without problems.
