gpiolib: Reuse device's fwnode to create IRQ domain
When IRQ domain is created for an ACPI case, the name of it becomes unknown-%d since for now it utilizes of_node member only and doesn't consider fwnode case. Convert IRQ domain creation code to utilize fwnode instead. Before/After the change on Intel Galileo Gen 2 with two GPIO (IRQ) controllers: unknown-1 ==> \_SB.PCI0.GIP0.GPO unknown-2 ==> \_SB.NIO3 Due to the nature of this change we may also deduplicate the WARN():s because in either case (DT or ACPI) the fwnode will be set correctly and %pfw is an equivalent to what the current code prints as a prefix.
