Pin setup may be optional in some cases such as the reset default works or the pin setup is done by the bootloader. In these cases, it is optional for the OS to support managing the pin controller and pin setup. In order to support this scenario, add a property 'pinctrl-use-default' to indicate that the pin configuration is optional.
