THis patch (as1022) adds stub methods for suspend/resume/reset_resume
and pre-rreset/post-reset to the usbfs_driver. There isn't much they
can do, since there's no way to inform a user task about any of these
events. But it's important to have the stubs, because an upcoming
change to usbcore will automatically unbind drivers that don't have
these methods.
