A3U/A5U both use a Bosch BMC150 accelerometer/magnetometer combo.
The chip provides two separate I2C devices for the accelerometer
and magnetometer that are already supported by the bmc150-accel
and bmc150-magn driver.

The only difference between A3U/A5U is the way the sensor is
mounted on the mainboard - set the mount-matrix in the
device-specific device tree part to handle that difference.
