Input: atmel_mxt_ts - Implement vector/orientation support
The atmel touch messages contain orientation information as a byte in a packed
format which can be passed straight on to Android if the input device
configuration is correct, see
http://source.android.com/tech/input/touch-devices.html#touchorientationcalibration
This requires vector reports to be enabled in maXTouch config (zero DISVECT
bit in T9 CTRL field)
Android converts the format in frameworks/base/services/input/Input.cpp,
search for ORIENTATION_CALIBRATION_VECTOR.
