When a device is suspended, cros_ec_handle_event will not check MKBP events. Instead, received MKBP events are checked during resume by cros_ec_report_events_during_suspend. But cros_ec_report_events_during_suspend cannot notify the PM if received events are wake events, causing wake events to not be reported if received while the device is suspended. Update cros_ec_report_events_during_suspend to notify the PM of wake events during resume by calling pm_wakeup_event.
