iio:common:ssp_sensors: Move exports into IIO_SSP_SENSORS 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 various specific device drivers that use them.

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

Both the exports used between the two common modules and the individual
drivers are moved to a single namespace as greater granularity does
not feel useful.
