The old driver was bad in many respect, it had some race conditions, it was using a thread to serialize transfers because of the legacy i2c interface. It also had huge latency (typically 50ms but delays up to 300ms can happen), thus some presses were missed. The new driver takes advantage of the new i2c driver to do everything asynchronously. It also does not need a thread anymore because queueing ensures proper serialization. It provides much better and reliable latency (typically ~2ms). Also fix the debug screen which was horribly broken. The new screen also displays the deadzones. Change-Id: I69b7f99b75053e6b1d3d56beb4453c004fd2076e
