This is totally wrong. The gpio driver needs these interrupts, and
will register a chained interrupt handle for these. Don't mess around
with them. Here is the code in the driver:

        /* Setup the interrupt handlers. Each chip can have up to 4
         * interrupt handlers, with each handler dealing with 8 GPIO
         * pins. */
        for (i = 0; i < 4; i++) {
                int irq = platform_get_irq(pdev, i);

                if (irq < 0)
                        continue;
                irq_set_handler_data(irq, mvchip);
                irq_set_chained_handler(irq, mvebu_gpio_irq_handler);
        }
