soundwire: stream: add alloc/config/free helpers for ports

Browse source

The existing code only has a config helper that allocates memory,
start adding alloc/config/free for ports, as a first step in the
simplification of the stream API.

This change removes a kfree() on a configuration error, this should
have not impact on existing platforms and error handling will be
revisited in follow-up patches to make sure invalid configurations
have not impact on memory allocation.
