iio: magnetometer: st_magn: Add LSM303C 



The magnetometer part of ST LSM303C is similar (perhaps even identical)
to the already supported standalone LIS3MDL magnetometer, so just
add the new st,lsm303c-magn compatible for the existing definitions.

	  Say yes here to build support for STMicroelectronics magnetometers:

	  LSM303DLHC, LSM303DLM, LIS3MDL.

	  LSM303C, LSM303DLHC, LSM303DLM, LIS3MDL.



	  Also need to enable at least one of I2C and SPI interface drivers
