Device tree properties should be a hardware description. However,
about the "irq-index", it seems a software configuration. So, even if we would
like to submit such a patch to add the property, it will be rejected.

Also, even if we can add a new device tree property, we should keep backward compatible.
However, this patch seems to break a backward compatibility.

Unfortunately, I don't have alternative solutions how to configurate per-port irq though...
# Maybe configfs??
