Update MPU3050 kernel driver
1. Update MPU3050 drivers to Invensense MPU code update v3.3.4 ported from:
https://android.googlesource.com/kernel/msm.git/+/android-msm-sony-cm-jb-3.0
2. Enable LSM303DLHA and LSM303DLHM as MPU3050 slaves instead of fake BMA150 and AK8975
3. Proper LSM303DLHA and LSM303DLHM power management when acting as MPU3050 slaves
4. Gyro axis configuration changed
5. Updates to sensor setup by John Newby
