Xu Yang 451b15ed13 usb: chipidea: core: fix possible concurrent when switch role 
The user may call role_store() when driver is handling
ci_handle_id_switch() which is triggerred by otg event or power lost
event. Unfortunately, the controller may go into chaos in this case.
Fix this by protecting it with mutex lock.
