The GPIO interrupt controller registers are mapped to the wrong
offset in the DTSI. Fix the offset in the DTSI and enable the interrupt
controller in the DTS of the only AXG board enabled.

multiple compatible strings should be ordered:
- use the most specific compatible (the AXG one) first
- the the less specific ones

also why did you add the AXG compatible string in the s400 board .dts
instead of meson-axg.dtsi (which makes it available for all AXG
boards)?

Amlogic's patched 4.9 buildroot kernel uses 0xf080 - can you add a
short sentence to the description on which board you have tested this
(I assume you used the s400)

mindlessly copied and pasted from the GXL.

good point.

The datasheet reports a different offset. But I tested again on 0xf080
and it looks like 0xf080 is actually the correct one? Need to test this
better.

I'll follow this up with v2.
