In this patch [1], the GPIO controller add support for describing
hardware with a three-cell scheme:

    gpios = <&gpio instance offset flags>;

It also result describing interrupts in three-cell as this in DT:

    node {
            interrupt-parent = <&gpio>;
            interrupts = <instance hwirq irqflag>;
    }

This series try to extend describing interrupts with three-cell scheme.
The first patch will parse interrupt irq and flag from last two cells,
the second patch support finding irqdomain with interrupt instance info.
