In RuntimeEnabledFeatures.in, you should mark device motion as enabled for
testing rather than putting this code here.

Would you also be willing to add a comment here explaining that we shouldn't put
feature-specific enable flags here and that instead folks should set the
"status" attribute in RuntimeEnabledFetures.in appropriately?

Done.
