pinctrl: nomadik: rename secondary to latent
The "secondary irq" in the nomadik pin control driver is actually not secondary (as in: can occur any time alongside the ordinary irq), it is a latent IRQ. It is an IRQ that has occurred when the system was in sleep state and has been cached in a special register flagged from the low power management unit (PRCM).
