gpio: mvebu: make mvchip->irqbase signed for error handling
There is a bug in mvebu_gpio_probe() where we do:
mvchip->irqbase = irq_alloc_descs(-1, 0, ngpios, -1);
if (mvchip->irqbase < 0) {
The problem is that mvchip->irqbase is unsigned so the error handling
doesn't work. I have changed it to be a regular int.
