I don't have access to the documentation so I'll leave that for you guys
to determine. I do note that the downstream DT does not use it and that
we have a new devicetree in linux-next which also does not have it:
https://lore.kernel.org/r/20240125-topic-sm8650-upstream-pcie-its-v1-1-cb506deeb43e@linaro.org
But at least the latter looks like an omission that should be fixed.
