Various fixes to Atmel's high speed UDC driver. * Issue some missing disconnect() calls. Currently they are only made when VBUS power goes away (on boards where the driver can sense such changes), but that's not enough for gadget drivers to clean out all the state that's needed. Missing calls were: - After USB reset, before starting enumeration. - When unregistering a gadget driver, before unbind(). * Don't assume gadget drivers provide disconnect callbacks; make sure to not call through a null pointer! * When the driver doesn't provide an unbind() callback, refuse to unregister it. Also remove two bogus "error" messages: * Related to mis-handling of disconnect() ... don't emit error messages for disconnect() handlers that disable endpoints. All of them should be doing that; the problem is (unfixed) oddness in atmel_usba_udc. * Don't emit a diagnostic for a curious and transient nonfatal error that shows up sometimes with EP0. Those messages spammed syslog, for no good reason.
