iio: magn: Add support for BMC150 magnetometer 

Add support for the Bosh BMC150 Magnetometer.
The specification can be downloaded from:
http://ae-bst.resource.bosch.com/media/products/dokumente/bmc150/BST-BMC150-DS000-04.pdf

.
The chip contains both an accelerometer and a magnetometer.
This patch adds support only for the magnetometer part.

The temperature compensation formulas are based on bmm050_api.c

	  Say yes here to build support for the BMC150 magnetometer.



	  Currently this only supports the device via an i2c interface.



	  This is a combo module with both accelerometer and magnetometer.

	  This driver is only implementing magnetometer part, which has

	  its own address and register map.
