pinctrl: samsung: s3c64xx: Ack level interrupts right before unmasking

The hardware will latch level triggered interrupts even while masked, so
unmasking an already inactive interrupt signal will trigger an interrupt.
In effect, even though the flow handler masks and acks the line, an
interrupt will be retriggered after unmasking it.

To fix this, this patch modifies the unmasking routine to ack an
interrupt before unmasking if it is level triggered. This will not
affect interrupts caused by really active interrupt line, because the
hardware will latch an active line state again after acking.
