tty: Use of_node_name_{eq,prefix} for node name comparisons
Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
For hvc, the code can also be simplified by using of_stdout pointer
instead of searching again for the stdout node.
