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

====================================
3
-
4
-
The Abilis TB10x SOC contains a custom interrupt controller. It performs
5
-
one-to-one mapping of external interrupt sources to CPU interrupts and
6
-
provides support for reconfigurable trigger modes.

Required properties
9
-
-------------------
10
-
11
-
- compatible: Should be "abilis,tb10x-ictl"
12
-
- reg: specifies physical base address and size of register range.
13
-
- interrupt-congroller: Identifies the node as an interrupt controller.
14
-
- #interrupt cells: Specifies the number of cells used to encode an interrupt
15
-
source connected to this controller. The value shall be 2.
16
-
- interrupts: Specifies the list of interrupt lines which are handled by
17
-
the interrupt controller in the parent controller's notation. Interrupts
18
-
are mapped one-to-one to parent interrupts.

/* ... */
