of: property: Document that of_graph_get_endpoint_by_regs needs of_node_put

Browse Source 
The node returned by of_graph_get_endpoint_by_regs has a reference taken,
and we need to put that reference back when done with the node.

However, the documentation for that node doesn't mention it, so let's make
sure it does.
