Orange Pi Zero support

[Jov]

Hi，
I have tried orangepi plus 2e imange and this can be used to boot and run
orange pi zero and one.All except ethernet works well.
I build uboot use this:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214729
and use crochet build the image.

I see a previous thread say dts files from linux can not be used on FreeBSD
directly and should be modified.

> I can also boot normally if the dtb file is rebuilt manually:

>   cpp -P -x assembler-with-cpp -I /usr/src/sys/gnu/dts/include -include
> sun8i-h3-orangepi-plus.dts /dev/null | dtc -O dtb -o ./sun8i-h3-rebuilt.dtb
>   ls -lh sun8i-h3-rebuilt.dtb
>   -rw-r--r--  1 root  wheel    15K Jun 24 13:02 sun8i-h3-rebuilt.dtb
> But, if dtb files from Armbian (Linux 4.11) are used, kernel will hang:

> 'boot/dtb-4.11.3-sun8i/sun8i-h2-plus-orangepi-zero.dtb'.
>   Kernel entry at 0x42200100...
>   Kernel args: -v
> The same file boots Linux without problems.
