Add a subnode to STM low power timer bindings to support timer driver

version 6:
- only use one interrupt

version 5:
- the previous has been acked-by Rob but since I have docummented
  interrupts and interrupt-names properties I haven't applied it here.

version 4:
- change compatible and subnode names
- document wakeup-source property
