Your first instinct is correct that it's unlikely that the community
will be able to maintain a device if it's really so niche as to only
be used at your organization.

However, if you do decide to try to upstream it, it could only help
your chances if you or some of your colleagues agreed to maintain it
for the QEMU community. This mainly involves adding an entry to the
MAINTAINERS file where, if accepted, the expectation is that you'll
be reachable within reason to review patches, make pull requests,
help discuss bugs in the subsystem, etc.

Sorry I don't have a concrete "yes" or "no" for you; but I'd recommend
giving it a shot if you have the time.
