We did that 2 or 3 times in the past without commnts that it is not
desired so I wasn't aware that this would be special handling.

Merging binding and devicetree updates together looks to me like the
most sensible option since dtbs validation is the only testable
dependecy of dt binding updates.
Keeping them together ensures the dtbs validate without delaying
devicetree changes by one kernel release after the dt-bindings change
was merged.
I suppose it works out most of the time if the merge request is sent
only if it validates in next. That still depends on the merge order in
the merge window but -rc1 should be fine.

I'll consider devicetree validation as eventually valid from now on and
not care too much about it.
