[PATCH v2 11/11] ARM: S3C24XX: remove maskack irq ack funtions

In the past level irqs provided a special ack handler that also masked
the interrupt. But handle_level_irq also does mask-ack the interrupt
itself, so there is no need to keep this special ack function around.
We therefore can simplyfy the number of irq-chips again.
