upm: enable MMC35240 3-axis magnetic sensor library and example

Browse Source 
MMC35240 is 3-axis magnetic sensor from MEMSIC.

This sensor can measure magnetic fields within the full scale range of
+-24 Gauss (G).

The library provided is libupm-mmc35240.so
The example provided is mmc35240-example-cxx where it will print x,y,z axis
when trigger buffer data is ready. It's also print azimuth value.

This sensor requires calibration. Please shake the sensor in figure 8 pattern,
mmc35240-example will print the calibrated level.

As the sensor data is noisy, we have implemented denoise algorithm within the
sensor library.

The azimuth formula is provided by Han, He <he.han@intel.com>.
