As we intend to eventually get board related parameters from a configuration
file, this commit makes the GPIO numbers for data-ready pins be instance
variables instead of from C constant macros.
Another advantage of using instance variables in this context is the
possibility of using more than one LSM9DS0.
This adds the backend driver for LSM9DS0. This implementation is based on the
legacy driver coded by Víctor Mayoral Vilches (under folder LSM9DS0) and makes
some necessary adaptations and fixes in order to work properly. The legacy
driver folder was removed.
The new LSM9DS0 driver will consist of the AP_InertialSensor_L3GD20 and
the AP_InertialSensor_LSM303D. For that reason the old LSM9DS0
(consisting of gyro and accel+mag implemented on a single class) has
been moved to a folder.
Legacy LSM9DS0 didn't probe to receive "correct" data.
