[PATCH 8/8] iio: imu: lsm6dsx: Move exported symbols to the IIO_LSM6DSX namespace

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Avoid unnecessary pollution of the global symbol namespace by
moving library functions in to a specific namespace and import
that into the drivers that make use of the functions.
