irqchip/atmel-aic5: Use per chip mask caches in mask/unmask()
When masking/unmasking interrupts, mask_cache is updated and used later for suspend/resume. Unfortunately, it always was the mask_cache associated with the first irq chip which was updated. So when performing resume, only irqs 0-31 could be enabled.
