Hmm, our use case is separate device and host controllers on a Bay Trail
system.  We don't ever need to suspend the bus, since the roles are fixed.
Also, the system is running RT tasks and we don't want PM on.

Maybe the device-side USB option should be separate from the OTG option?  We
really don't want HNP or any of the dual-role features, just support for
gadget drivers and USB device controllers.
