PATCH 1/1 dt-bindings: interrupt-controller: Convert arm,nvic to DT schema

Convert the Arm NVIC interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller.

-* ARM Nested Vector Interrupt Controller (NVIC)
-
-The NVIC provides an interrupt controller that is tightly coupled to
-Cortex-M based processor cores.  The NVIC implemented on different SoCs
-vary in the number of interrupts and priority bits per interrupt.
-
-Main node required properties:
-
-- compatible : should be one of:
-	"arm,v6m-nvic"
-	"arm,v7m-nvic"
-	"arm,v8m-nvic"
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source.  The type shall be a <u32> and the value shall be 2.
-
-  The 1st cell contains the interrupt number for the interrupt type.
-
-  The 2nd cell is the priority of the interrupt.
-
-- reg : Specifies base physical address(s) and size of the NVIC registers.
-  This is at a fixed address (0xe000e100) and size (0xc00).
-
-- arm,num-irq-priority-bits: The number of priority bits implemented by the
-  given SoC
-
-Example:
-
-	intc: interrupt-controller@e000e100 {
-		compatible = "arm,v7m-nvic";
-		#interrupt-cells = <2>;
-		#address-cells = <1>;
-		interrupt-controller;
-		reg = <0xe000e100 0xc00>;
-		arm,num-irq-priority-bits = <4>;
-	};
