I wasn't sure either, but Rob was OK with not documenting some other
bindings which are only used for testing[0], so I assumed that that
applied here too:
[0] https://lore.kernel.org/all/5baa1ae6.1c69fb81.847f2.3ab1@mx.google.com/
Also, DT bindings are supposed to be generic and based on what the
hardware has, but here we have no hardware and something very Linux and
UML-specific.
