MIPS: Octeon: Make Octeon GPIO IRQ chip CPU hotplug-aware
Make Octeon GPIO IRQ chip CPU hotplug-aware Seems that irq_cpu_offline callbacks were forgotten in v1 and v2 CIU GPIO chips. There is such a callback for octeon_irq_chip_ciu2_gpio, covering CIU2 chips. Without this callback GPIO IRQs are not being migrated during core offlining. Patch is tested on Octeon II.
