iio:adc:ad_sigma_delta: Move exports into IIO_AD_SIGMA_DELTA namespace

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

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