[U-Boot] About convert to LIVE DT

Hi Simon, Philipp,

When I try to convert to live dt, I fount there are many APIs work in fdt are missing in live dt,

do you have any suggestion to add these APIs in live dt quickly? I need:

fdtdec_get_addr_size_auto_noparent fdt_alloc_phandle fdt_device_is_available fdt_for_each_subnode fdt_getprop fdt_getprop_u32_default_node fdt_get_named_resource fdt_get_name fdt_get_path fdt_get_phandle fdt_node_depth fdt_node_offset_by_phandle fdt_node_offset_by_phandle_node fdt_path_offset fdt_set_phandle fdt_stringlist_get fdt_stringlist_search fdt_subnode_offset fdt_supernode_atdepth_offset

Thanks,

- Kever
