usb: otg_id: add suspend/resume interface It is possible that while one driver has already suspended, another driver calls otg_id_notify() because it has not yet been suspended. It would then be possible for the suspended driver's detect callback to be called. This is undesirable. Introduce new otg_id_suspend/otg_id_resume functions that keep a suspended count, and if a notification happens while someone is suspended, that notification is deferred until all the drivers are resumed. If the notification happens before the last driver is suspended, that suspend will be aborted and once the final driver resumes through otg_id_resume, the notification will be delivered.
