I think it is unlikely there are bugs in the code to parse dtb files,
it is used for a lot of other boards.

The dts sources look wrong to me, the sun8i-h3-orangepi-one.dts patch
file references a local sun8i-h3.dtsi file that has been deleted.

The built dtb file under -current ends up with all the mmc nodes
disabled, could you try the patch below.

There seem to be a number of other nodes disabled too, like emac and
usb.
