Subject: [PATCH v3 3/7] gpio: gpio-ep93xx: Fix wrong irq numbers in port F

Port F irq's should be statically mapped to EP93XX_GPIO_F_IRQ_BASE.

So we need to specify girq->first otherwise:

"If device tree is used, then first_irq will be 0 and
irqs get mapped dynamically on the fly"

And that's not the thing we want.
