PATCH 1/1 dt-bindings: interrupt-controller: Convert microchip,pic32mzda-evic to DT schema

Convert the Microchip PIC32 interrupt controller binding to schema format. It's a straight-forward conversion of the typical interrupt controller.

-Microchip PIC32 Interrupt Controller
-====================================
-
-The Microchip PIC32 contains an Enhanced Vectored Interrupt Controller (EVIC).
-It handles all internal and external interrupts. This controller exists outside
-of the CPU and is the arbitrator of all interrupts (including interrupts from
-the CPU itself) before they are presented to the CPU.
-
-External interrupts have a software configurable edge polarity. Non external
-interrupts have a type and polarity that is determined by the source of the
-interrupt.
-
-Required properties
--------------------
-
-- compatible: Should be "microchip,pic32mzda-evic"
-- reg: Specifies physical base address and size of register range.
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt cells: Specifies the number of cells used to encode an interrupt
-  source connected to this controller. The value shall be 2 and interrupt
-  descriptor shall have the following format:
-
-	<hw_irq irq_type>
-
-  hw_irq - represents the hardware interrupt number as in the data sheet.
-  irq_type - is used to describe the type and polarity of an interrupt. For
-  internal interrupts use IRQ_TYPE_EDGE_RISING for non persistent interrupts and
-  IRQ_TYPE_LEVEL_HIGH for persistent interrupts. For external interrupts use
-  IRQ_TYPE_EDGE_RISING or IRQ_TYPE_EDGE_FALLING to select the desired polarity.
-
-Optional properties
--------------------
-- microchip,external-irqs: u32 array of external interrupts with software
-  polarity configuration. This array corresponds to the bits in the INTCON
-  SFR.
-
-Example
--------
-
-evic: interrupt-controller@1f810000 {
-	compatible = "microchip,pic32mzda-evic";
-	interrupt-controller;
-	#interrupt-cells = <2>;
-	reg = <0x1f810000 0x1000>;
-	microchip,external-irqs = <3 8 13 18 23>;
-};
-
-Each device/peripheral must request its interrupt line with the associated type
-and polarity.
-
-Internal interrupt DTS snippet
-------------------------------
-
-device@1f800000 {
-	...
-	interrupts = <113 IRQ_TYPE_LEVEL_HIGH>;
-	...
-};
-
-External interrupt DTS snippet
-------------------------------
-
-device@1f800000 {
-	...
-	interrupts = <3 IRQ_TYPE_EDGE_RISING>;
-	...
-};
