Document the fact that some Exynos PMUs are capable of acting as
an interrupt controller.

+Some PMUs are capable of behaving as an interrupt controller (mostly
+to wake up a suspended PMU). In which case, they can have the
+following properties:
+
+- interrupt-controller: indicate that said PMU is an interrupt controller
+
Need to add #interrupt-cells property here.

+- interrupt-parent: a phandle indicating which interrupt controller
+  this PMU signals interrupts to.
+
  Example :
  pmu_system_controller: system-controller at 10040000 {
  	compatible = "samsung,exynos5250-pmu", "syscon";
  	reg = <0x10040000 0x5000>;
+	interrupt-controller;
+	interrupt-parent = <&gic>;
  	#clock-cells = <1>;
  	clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
  			"clkout4", "clkout8", "clkout9";
