[PATCH v8 41/45] drivers/of: Avoid recursively calling unflatten_dt_node()

In current implementation, unflatten_dt_node() is called recursively to unflatten device nodes in FDT blob. It's stress to limited stack capacity, especially to adopt the function to unflatten device sub-tree that possibly has multiple root nodes. In that case, we runs out of stack and the system
