sunxi: Add support for OrangePi Zero2
OrangePi Zero2 is SBC based on Allwinner H616 with 1 GiB of RAM, SD card support, gigabit ethernet, micro HDMI, WIFI, Bluetooth and 1 USB 2.0 port. It also has two GPIO headers which allows further peripherals to be used. The devicetree file is taken from v3 of the OrangePi Zero2 Linux submission [1], which it's not yet merged.
