Add an irqdomain for the AIC interrupt controller.
The device tree support is mapping the registers and
is using the irq_domain_simple_ops to manage hwirq
translation.
The documentation is describing the meaning of the
two cells required for using this "interrupt-controller"
in a device tree node.

This patch should go on top of Jamie's patch:
"irqdomain: export irq_domain_simple_ops for !CONFIG_OF"
https://lkml.org/lkml/2011/12/1/109

v3: - change number of cells to define an AIC interrupt (irq trigger type)
    - change current .dtsi files to match specification
    - use irq_domain_simple_ops (for DT mapping)

v2: - use of_irq_init() function for device tree probing
    - add documentation
    - use own simple struct irq_domain_ops

just one stuff missing the definition of the external irq
