In 3.3, gpio wakeup setting was broken. The call enable_irq_wake() didn't set up the PXA gpio registers (PWER, ...) anymore. Fix it at least for pxa27x. The driver doesn't seem to be used in pxa25x (weird ...), and the fix doesn't extend to pxa3xx and pxa95x (which don't have a gpio_set_wake() available).
