add_mtd_partitions_of() creates MTD partition slaves from device-tree sub-nodes but never stores the originating ofnode on the partition. This means there is no way to match a registered MTD partition back to its DT node.
Set slave->flash_node = child right after allocate_partition() so that every DT-created partition carries a reference to its DT node. This will be used by the image_loader UBI backend to find the MTD partition that corresponds to a 'compatible = "linux,ubi"' node.
