A series about interrupt controller cleanup. AT91 AIC is moving to 

fasteoi type of handler and sparse IRQ.
 The Device Tree support is added to take into account priority
 and external IRQ.
 In addition to that, the new AIC5 IP is introduced.

- #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
