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.
