[Patch v5 05/12] irqchip: xilinx: Try to fall back if xlnx,kind-of-intr not provided

[Zubair Lutfullah Kakakhel]

The powerpc dts file upstream does not have the xlnx,kind-of-intr
property. Instead of erroring out, give a warning instead.
And attempt to continue to probe the interrupt controller while
assuming kind-of-intr is 0x0 as a fall back.
