dt-bindings: interrupt-controller: Convert abilis,tb10x-ictl to DT schema

Convert the Abilis TB10x interrupt controller binding to schema format.
It's a straight-forward conversion of the typical interrupt controller.

-TB10x Top Level Interrupt Controller
-====================================
-
-The Abilis TB10x SOC contains a custom interrupt controller. It performs
-one-to-one mapping of external interrupt sources to CPU interrupts and
-provides support for reconfigurable trigger modes.
-
-Required properties
--------------------
-
-- compatible: Should be "abilis,tb10x-ictl"
-- reg: specifies physical base address and size of register range.
-- interrupt-congroller: 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.
-- interrupts: Specifies the list of interrupt lines which are handled by
-  the interrupt controller in the parent controller's notation. Interrupts
-  are mapped one-to-one to parent interrupts.
-
-Example
--------
-
-intc: interrupt-controller {	/* Parent interrupt controller */
-	interrupt-controller;
-	#interrupt-cells = <1>;	/* For example below */
-	/* ... */
-};
-
-tb10x_ictl: pic@2000 {		/* TB10x interrupt controller */
-	compatible = "abilis,tb10x-ictl";
-	reg = <0x2000 0x20>;
-	interrupt-controller;
-	#interrupt-cells = <2>;
-	interrupt-parent = <&intc>;
-	interrupts = <5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
-			20 21 22 23 24 25 26 27 28 29 30 31>;
-};
