pinctrl: sunxi: Mark the irq bank not found in sunxi_pinctrl_irq_handler() with WARN_ON
The interrupt descriptor cannot be found in the interrupt processing function, and this situation cannot happen when the system is running normally. It doesn't seem right to return directly to the status of not handling gic. In this case, it must be a bug, let's mark it with WARN_ON.
