Support for USB 3.0 hub suspend.

This patchset adds support for suspending external USB 3.0 hubs, and fixes the
USB 3.0 device remote wakeup enabling.  Hubs are the only USB 3.0 devices on
the market right now that do remote wakeup, and they will only send a remote
wakeup if they are placed into suspend, so it's not necessary to backport this
patchset to stable kernels.
