MediaTek sysirq

MediaTek SOCs sysirq support controllable irq inverter for each GIC SPI
interrupt.

- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
- reg: Physical base address of the intpol registers and length of memory
  mapped region. Could be multiple bases here. Ex: mt6797 needs 2 reg, others
  need 1.

Example:
	sysirq: intpol-controller@10200620 {
		compatible = "mediatek,mt6797-sysirq",
			     "mediatek,mt6577-sysirq";
		interrupt-controller;
		#interrupt-cells = <3>;
		interrupt-parent = <&gic>;
		reg = <0 0x10220620 0 0x20>,
		      <0 0x10220690 0 0x10>;
	};
