ARM: 5970/1: nomadik-gpio: fix spinlock usage

Fix the incorrect spinlock usage which leads to these compiler warnings:

arch/arm/plat-nomadik/gpio.c:60: warning: passing argument 1 of `spinlock_check' from incompatible pointer type
arch/arm/plat-nomadik/gpio.c:69: warning: passing argument 1 of `spin_unlock_irqrestore' from incompatible pointer type
