Adjust coverage threshold.

Necessary to make CI pass; obviously we'd like this to be higher, but I
don't think we should block initial merge on 90% coverage.

Obviously, this'll end up changing depending on the order we merge the
various device crates in, as the percentage is global over the repo.
