iio: accel: mma8452: Add missing documentation for name element of chip_info

Documentation needed to avoid build warning with W=1 builds. It doesn't
really add any non obvious information but good to have it anyway.

No fixes tag as not worth backporting onto the fix that added the name
element to the structure.
