Yeah.

What you need to have is
1) expand fwnode_irq_get() to support ACPI GPIO IRQ resources.
2) provide a simple version of the fwnode_irq_get_by_name() like

	if (is_of_node())
		return of_...();

	return acpi_dev_gpio_irq_get_by();

3) establish understanding about naming for ACPI and
4) extend fwnode_irq_get_by_name() by it

	if (is_of_node())
		return of_...();

	ret = acpi_irq_get_by_name();
	if (ret > 0)
		return ret;

	return acpi_dev_gpio_irq_get_by();

As I mentioned, items 1 and 2 are easy to achieve with currently existing APIs.
