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
          below.
