[PATCH v2 1/1] dt-bindings: interrupt-controller: fsl,ls-extirq: workaround wrong interrupt-map number

[Frank Li <Frank.Li@nxp.com>]

The driver(drivers/irqchip/irq-ls-extirq.c) have not use standard DT
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 and maxItems to workaround this warning for
'fsl,ls1088a-extirq', 'fsl,ls2080a-extirq' and fsl,lx2160a-extirq.
Other keep the same restriction.

Change from v1 to v2
- remove duplicate function in commit message
- only reduce miniItems for after 1088a chips
- maxItems change to 9. Otherwise report too long.
