Allwinner A20/A31 SoCs have a special interrupt controller for managing NMI.
Three register are present to (un)mask, control and acknowledge NMI.
These two patches add a new irqchip driver in cascade with GIC.

Changes since v1:
	- added binding document

Changes since v2:
	- fixed trigger type in DTS
	- new explanations in binding documentation
	- added support for A31 (sun6i)

Changes since v3:
	- changed compatibles

  ARM: sun7i/sun6i: dts: Add NMI irqchip support
