irqchip: atmel-aic: Move binding doc to interrupt-controller directory
Move atmel aic driver doc to the interrupt-controller directory as the new driver now lays in drivers/irqchip/atmel-aic.c.

-* Advanced Interrupt Controller (AIC)
-
-Required properties:
-- compatible: Should be "atmel,<chip>-aic"
- <chip> can be "at91rm9200" or "sama5d3"
-- interrupt-controller: Identifies the node as an interrupt controller.
-- interrupt-parent: For single AIC system, it is an empty property.
-- #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).
- The second cell is used to specify flags:
- bits[3:0] trigger type and level flags:
- 1 = low-to-high edge triggered.
- 2 = high-to-low edge triggered.
- 4 = active high level-sensitive.
- 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.

- aic: interrupt-controller@fffff000 {

- interrupt-parent;

- reg = <0xfffff000 0x200>;
- };

- /*
- * An interrupt generating device that is wired to an AIC.

- dma: dma-controller@ffffec00 {
- compatible = "atmel,at91sam9g45-dma";
- reg = <0xffffec00 0x200>;
- interrupts = <21 4 5>;
