iio:magnetometer:rm3100: Move exports to IIO_RM3100 namespace

Browse Source 
In order to avoid unnecessary pollution of the global symbol namespace
move the common/library functions into a specific namespace and import
that into the bus specific device drivers that use them.

For more information see https://lwn.net/Articles/760045/
