* NXP i.MX8QM/i.MX8QXP IRQSteer Interrupt Controllers

Required properties:
- compatible: "nxp,imx-irqsteer".
- reg: should contain IC registers location and length.
- clocks : ipg clock for irqsteer.
- interrupts: an interrupt to the parent interrupt controller.
- interrupt-controller: identifies the node as an interrupt controller.
- interrupt-parent: gic interrupt controller, link to parent
- #interrupt-cells: the number of cells to define an interrupt, should be 2.
  The first cell is the IRQ number, the second cell is used to specify
  one of the supported IRQ types:
      IRQ_TYPE_EDGE_RISING = low-to-high edge triggered,
      IRQ_TYPE_EDGE_FALLING = high-to-low edge triggered,
      IRQ_TYPE_LEVEL_HIGH = active high level-sensitive,
      IRQ_TYPE_LEVEL_LOW = active low level-sensitive.

Optional properties:
- nxp,irqsteer_chans: specify the interrupt channel number, default is 1.

Examples:

	irqsteer_hdmi: irqsteer@56260000 {
		compatible = "nxp,imx-irqsteer";
		reg = <0x0 0x56260000 0x0 0x1000>;
		interrupts = <GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>;
		interrupt-controller;
		interrupt-parent = <&gic>;
		#interrupt-cells = <2>;
		power-domains = <&pd_hdmi_i2c0>;
	};

	i2c0_hdmi: i2c@56266000 {
		compatible = "fsl,imx8qm-lpi2c";
		reg = <0x0 0x56266000 0x0 0x1000>;
		interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
		interrupt-parent = <&irqsteer_hdmi>;
		clocks = <&clk IMX8QM_HDMI_I2C0_CLK>;
		clock-names = "per";
		assigned-clocks = <&clk IMX8QM_HDMI_I2C0_CLK>;
		assigned-clock-rates = <24000000>;
		power-domains = <&pd_hdmi_i2c0>;
		status = "disabled";
	};
