At present the structures are written in name order, but parents have to be written before their children, so the file does not end up being in order. The order of nodes in _valid_nodes matches the order of the devicetree.
Update the code so that _valid_nodes is in sorted order, by C name of the structure. This allows us to assign a sequential ordering to each U_BOOT_DEVICE() declaration.
U-Boot's linker lists are also ordered alphabetically, which means that the order in the driver_info list will match the order used by dtoc. This defines an index ('idx') for the U_BOOT_DEVICE declarations. They appear in alphabetical order, numbered from 0 in _valid_nodes and in the driver_info linker list.
Add a comment against each declaration, showing the idx value.

Applied to u-boot-dm, thanks!
