TTRX_3485 requires the infamous "dummy job" workaround. I have this
workaround implemented in a local branch, but I have not yet hit a case
that requires it so I cannot test whether the implementation is correct.
In the mean time, add the quirk bit so we can document which platforms
may need it in the future.
