[PATCH 1/1] dt-bindings: interrupt-controller: fsl,ls-extirq: workaround wrong interrupt-map number

[Frank Li]

The driver(drivers/irqchip/irq-ls-extirq.c) have not use standard DT
function function to parser interrupt-map. So it doesn't consider
'#address-size' in parent interrupt controller, such as GIC.

When dt-binding verify interrupt-map, item data matrix is spitted at
incorrect position. So cause below warning:

arch/arm64/boot/dts/freescale/fsl-ls1088a-qds.dtb: interrupt-controller@14:
interrupt-map: [[0, 0, 1, 0, 0, 4, 1, 0], [1, 0, 1, 4, 2, 0, 1, 0], ...
is too short

Reduce minItems to workaround this warning.
