lsm9ds0: Initial implementation

This module implements support for the LSM9DS0 accelerometer,
magnetometer, and gyroscope.

It was developed on the Sparkfun 9DOF sensor block for Intel Edison.

https://www.sparkfun.com/products/13033

Commonly used capabilities are supported, and methods/register
definitions exist to easily implement any desired functionality that
is missing.  Interrupt support has also been added.
