PATCH 1/1 dt-bindings: interrupt-controller: Convert hisilicon,mbigen-v2 to DT schema

Convert the HiSilicon MBIGEN binding to DT schema format. It's a straight-forward conversion.

-Hisilicon mbigen device tree bindings.
-=======================================
-
-Mbigen means: message based interrupt generator.
-
-MBI is kind of msi interrupt only used on Non-PCI devices.
-
-To reduce the wired interrupt number connected to GIC,
-Hisilicon designed mbigen to collect and generate interrupt.
-
-
-Non-pci devices can connect to mbigen and generate the
-interrupt by writing ITS register.
-
-The mbigen chip and devices connect to mbigen have the following properties:
-
-Mbigen main node required properties:
--------------------------------------------
-- compatible: Should be "hisilicon,mbigen-v2"
-
-- reg: Specifies the base physical address and size of the Mbigen
-  registers.
-
-Mbigen sub node required properties:
-------------------------------------------
-- interrupt controller: Identifies the node as an interrupt controller
-
-- msi-parent: Specifies the MSI controller this mbigen use.
-  For more detail information,please refer to the generic msi-parent binding in
-  Documentation/devicetree/bindings/interrupt-controller/msi.txt.
-
-- num-pins: the total number of pins implemented in this Mbigen
-  instance.
-
-- #interrupt-cells : Specifies the number of cells needed to encode an
-  interrupt source. The value must be 2.
-
-  The 1st cell is hardware pin number of the interrupt.This number is local to
-  each mbigen chip and in the range from 0 to the maximum interrupts number
-  of the mbigen.
-
-  The 2nd cell is the interrupt trigger type.
-	The value of this cell should be:
-	1: rising edge triggered
-	or
-	4: high level triggered
-
-Examples:
-
-	mbigen_chip_dsa {
-			compatible = "hisilicon,mbigen-v2";
-			reg = <0x0 0xc0080000 0x0 0x10000>;
-
-			mbigen_gmac:intc_gmac {
-				interrupt-controller;
-				msi-parent = <&its_dsa 0x40b1c>;
-				num-pins = <9>;
-				#interrupt-cells = <2>;
-			};
-
-			mbigen_i2c:intc_i2c {
-				interrupt-controller;
-				msi-parent = <&its_dsa 0x40b0e>;
-				num-pins = <2>;
-				#interrupt-cells = <2>;
-			};
-	};
-
-Devices connect to mbigen required properties:
-----------------------------------------------------
--interrupts:Specifies the interrupt source.
- For the specific information of each cell in this property,please refer to
- the "interrupt-cells" description mentioned above.
-
-Examples:
-	gmac0: ethernet@c2080000 {
-		#address-cells = <1>;
-		#size-cells = <0>;
-		reg = <0 0xc2080000 0 0x20000>,
-		      <0 0xc0000000 0 0x1000>;
-		interrupt-parent  = <&mbigen_device_gmac>;
-		interrupts =	<656 1>,
-				<657 1>;
-	};
