The combination of the enable-active-high and enable-at-boot properties
ought be able to cause the driver to do the right thing, the flags do
this:

	if (config->enabled_at_boot) {
		if (config->enable_high)
			cfg.ena_gpio_flags |= GPIOF_OUT_INIT_HIGH;
		else
			cfg.ena_gpio_flags |= GPIOF_OUT_INIT_LOW;
	} else {
		if (config->enable_high)
			cfg.ena_gpio_flags |= GPIOF_OUT_INIT_LOW;
		else
			cfg.ena_gpio_flags |= GPIOF_OUT_INIT_HIGH;
	}

of_get_named_gpio() just looks up the GPIO number, it doesn't request
the GPIO.
