Just to clarify this - bindings are not about the driver, but about the
hardware. We model here the hardware and its programming model, not the
driver implementation (although of course it's always somehow related).
Hardware has some limitations for sure. The question is whether we know
them. :)

I prefer even arbitrary limit, because then schema will check DTSes for
simple mistakes. You can also explain this in commit msg, that maxItems
are arbitrary, so whoever in the future wants to change it, will know
the background.

Best regards,
Krzysztof
