Actions Semi Owl family SoC's S500, S700 and S900 provides support
for 3 external interrupt controllers through SIRQ pins.

Each line can be independently configured as interrupt and triggers
on either of the edges (raising or falling) or either of the levels
(high or low) . Each line can also be masked independently.
