irqchip: Add support for TI-NSPIRE irqchip
This patch adds support for the interrupt controllers found in some TI-Nspire models. FIQ support was taken out to simplify the driver code and may be added in later. Since Linux on this platform doesn't really use FIQs, this wasn't really that important in the first place.

+TI-NSPIRE interrupt controller
+
+Required properties:
+- compatible: Compatible property value should be "lsi,zevio-intc".
+
+- reg: Physical base address of the controller and length of memory mapped
+ region.
+
+- interrupt-controller : Identifies the node as an interrupt controller
+
+Example:
+
+interrupt-controller {
+ compatible = "lsi,zevio-intc";
+ interrupt-controller;
+ reg = <0xDC000000 0x1000>;
+ #interrupt-cells = <1>;
+};
