HACK: libsensors: Initial attempt at MotionApps 5.1 for MPU6050 + AKM8975

The code in this patch still needs work.
But checking it in will allow other parts of the sensor stack to have
something to work with.

1. Have sensor HAL for IIO driver, which uses MPU6050 + AKM8975 (on 2nd bus).
2. Include MPL binaries (libmllite.so/libmplmpu.so).
3. Include necessary header files.
4. remove light sensor dependency.
5. add missing include file.
6. modify the module name into "manta".
7. remove mlsdk directory.
8. Fix some known issues.
9. Sync up to June.12.
10. Tweak slightly so that it can be used with other sensors on manta.
