[PATCH] fdt: fix phandles not copying when using templates

[Anshul Dalal]

The phandles used inside a template were not being copied to the node
inserting the template, leading to a missing phandle error.

The following example can be used to reproduce the issue:

&binman {
  some_template: template-0 {
    ti-secure-rom {
      content = <&some_data>;
      keyfile = "some_key";
    };
    some_data: blob-ext {
      optional;
    };
  };
  output-bin {
    insert-template = <&some_template>;
  };
};

With the error 'binman: Node '/binman/output-bin/ti-secure-rom': Cannot
find node for phandle 103' observed.
