Subject: [PATCH v3 3/4] arm64: dts: actions: Add sirq node for Actions Semi S700

Add sirq node for Actions Semi S700 SoC with 3 SIRQ pins support,
in which external interrupt controllers can be connected.

Example:
atc260x: atc2603c@65 {
        interrupt-parent = <&sirq>;
        interrupts = <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>;
};
