CRISv32: Fix typo compile error in ARTPEC-3 gpio driver.

arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);
arch/cris/arch-v32/drivers/mach-a3/gpio.c:
+spin_lock_irqrestore(&gpio_lock, flags);

  should that not be "spin_unlock_irqrestore()"?

The code in question was inside an (most often) undefined ifdef.
