* Advanced Interrupt Controller (AIC)
Required properties:
- compatible: Should be "atmel,<chip>-aic"
<chip> can be "at91rm9200", "sama5d2", "sama5d3" or "sama5d4"
- compatible: Should be:
- "atmel,<chip>-aic" where <chip> can be "at91rm9200", "sama5d2",
"sama5d3" or "sama5d4"
- "microchip,<chip>-aic" where <chip> can be "sam9x60"
- interrupt-controller: Identifies the node as an interrupt controller.
- #interrupt-cells: The number of cells to define the interrupts. It should be 3.
The first cell is the IRQ number (aka "Peripheral IDentifier" on datasheet).
