of: Add function to duplicate a device tree
This adds of_dup() to duplicate a device tree. Previously of_copy_node()
was used for this, but of_copy_node() has issues with potentially
duplicated phandle values when the new tree is inserted to an existing
tree, that is when the parent argument of of_copy_node() is non NULL.
All users of of_copy_node() with a NULL parent argument are converted
to of_dup() which is safe to use leaving only the problematic users
of of_copy_node().
