Add support to parse static master port map information from device tree.
This is required for correct port mapping between soundwire device and
master ports.

Same comment. Either dev_warn (if it's something to warn about) or
dev_info.

Or, as your commit message mentions that it is required, it should be an
error if the port mapping is not specified.

This is an optional property for older SoCs which have 1:1 port map between device and master.
