Subject: [PATCH v5 17/17] soundwire: intel: use EXPORT_SYMBOL_NS

The soundwire-intel module exports an 'intel_sdw_driver' structure,
which is declared with a namespace explicitly imported by the
soundwire-intel-init module.

The use of namespaces might be deemed overkill here, but it did help
enforce a proper code partitioning for follow-up patches on clock-stop
support.
