dt-bindings: iommu: arm,smmu-v3: Relax order of interrupt names
The QEMU devicetree uses a different order for SMMUv3 interrupt names,
and there isn't a good reason for enforcing a specific order. Since all
interrupt lines are optional, operating systems should not expect a
fixed interrupt array layout; they should instead match each interrupt
to its name individually. Besides, as a result of commit e4783856a2e8
("dt-bindings: iommu: arm,smmu-v3: make PRI IRQ optional"), "cmdq-sync"
and "priq" are already permutable. Relax the interrupt-names array
entirely by allowing any permutation, incidentally making the schema
more readable.
Note that dt-validate won't allow duplicate names here so we don't need
to specify maxItems or add additional checks, it's quite neat.
