Some GPIO pinctrl nodes cannot be easily removed, because they would also change the pin configuration, for example to add a pull resistor or change the current delivered by the pin. Those nodes still have underscores and unit-addresses in their node names in our DTs, so adjust their name to remove the warnings. Use that occasion to also fix some poorly chosen node-names.
