sensors: Fix conversion values

Browse source 
Our kernel sets the gyro to 500 DPS and not 2000 DPS.
In addition, X and Y are swapped and Y is not inverted.

Also change the orientation sensor conversion factors to
match that found in aries-common since the orientation
sensor seemed overly sensitive.  However, the orientation
sensor might not actually do anything...  Android may
be performing sensor fusion of other data to determine
orientation.
