dt-bindings: interrupt-controller: Convert marvell,orion-bridge-intc to DT schema

Convert the Marvell Orion bridge interrupt controller binding to schema
format.

marvell,orion-intc is already covered by mrvl,intc.yaml schema, so it
can be dropped.

-Marvell Orion SoC interrupt controllers
-
-* Main interrupt controller
-
-Required properties:
-- compatible: shall be "marvell,orion-intc"
-- reg: base address(es) of interrupt registers starting with CAUSE register
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: number of cells to encode an interrupt source, shall be 1
-
-The interrupt sources map to the corresponding bits in the interrupt
-registers, i.e.
-- 0 maps to bit 0 of first base address,
-- 1 maps to bit 1 of first base address,
-- 32 maps to bit 0 of second base address, and so on.
-
-Example:
-	intc: interrupt-controller {
-		compatible = "marvell,orion-intc";
-		interrupt-controller;
-		#interrupt-cells = <1>;
-		 /* Dove has 64 first level interrupts */
-		reg = <0x20200 0x10>, <0x20210 0x10>;
-	};
-
-* Bridge interrupt controller
-
-Required properties:
-- compatible: shall be "marvell,orion-bridge-intc"
-- reg: base address of bridge interrupt registers starting with CAUSE register
-- interrupts: bridge interrupt of the main interrupt controller
-- interrupt-controller: identifies the node as an interrupt controller
-- #interrupt-cells: number of cells to encode an interrupt source, shall be 1
-
-Optional properties:
-- marvell,#interrupts: number of interrupts provided by bridge interrupt
-      controller, defaults to 32 if not set
-
-Example:
-	bridge_intc: interrupt-controller {
-		compatible = "marvell,orion-bridge-intc";
-		interrupt-controller;
-		#interrupt-cells = <1>;
-		reg = <0x20110 0x8>;
-		interrupts = <0>;
-		/* Dove bridge provides 5 interrupts */
-		marvell,#interrupts = <5>;
