+Android Goldfish PIC

+Android Goldfish programmable interrupt device used by Android
+emulator.

+Required properties:
+
+- compatible : should contain "google,goldfish-pic"
+- reg        : <registers mapping>
+- interrupts : <interrupt mapping>
+
+Example for mips when used in cascade mode:
+
+        cpuintc {
