dt-bindings: interrupt-controller: via,vt8500-intc: Convert to YAML



Rewrite the textual description for the VIA/WonderMedia interrupt
controller as YAML schema.

The original textual version did not contain information about the
usage of 'interrupts' to describe the connection of a chained
controller to its parent, add it here. A chained controller can
trigger up to 8 different interrupts (IRQ0~7) on its parent.

VIA/Wondermedia VT8500 Interrupt Controller
-----------------------------------------------------

Required properties:
- compatible : "via,vt8500-intc"
- reg : Should contain 1 register ranges(address and length)
- #interrupt-cells : should be <1>

Example:

	intc: interrupt-controller@d8140000 {
		compatible = "via,vt8500-intc";
		interrupt-controller;
		reg = <0xd8140000 0x10000>;
		#interrupt-cells = <1>;
	};

title: VIA and WonderMedia SoCs Interrupt Controller

description:
  This is the interrupt controller used in single-core ARM SoCs made by
  VIA and WonderMedia (up to and including WM8950). Each block handles
  up to 64 interrupt sources (level or edge triggered) and can generate
  up to 8 interrupts to its parent when used in a chained configuration.
