USB: musb: silence "suspend as a_wait_vrise is_active" msgs
Get rid of some obnoxious and inappropriate messaging, mostly on DaVinci, when usbcore tries to autosuspend a root hub if just a mini/micro-A connector is connected. Symptom: endless stream of messages reading like: musb_bus_suspend 2221: trying to suspend as a_wait_vrise is_active=1 Improve that musb bus suspend primitive a bit. Take advantage of this call to update the OTG state machine if appropriate, moving the device out of the A_WAIT_VRISE state. There's basically no timer for that state transition just now, except with tusb6010; that can make trouble.
