Input: allow drivers specify timestamp for input events
Currently, evdev stamps events with timestamps acquired in evdev_events() However, this timestamping may not be accurate in terms of measuring when the actual event happened. Let's allow individual drivers specify timestamp in order to provide a more accurate sense of time for the event. It is expected that drivers will set the timestamp in their hard interrupt routine.
