- #interrupt-cells: The number of cells to define the interrupts. It sould be 3.
The first cell is the IRQ number (aka "Peripheral IDentifier" on datasheet).
The second cell is used to specify flags:

8 = active low level-sensitive.
Valid combinations are 1, 2, 3, 4, 8.
Default flag for internal sources should be set to 4 (active high).
The third cell is used to specify the irq priority from 0 (lowest) to 7
(highest).
- reg: Should contain AIC registers location and length
- atmel,external-irqs: u32 array of external irqs.
