Currently the bus does not have any explicit support for master devices. Add explicit support for sdw_slave_type, so that in follow-up patches we can add support for the sdw_md_type (md==Master Device), following the Grey Bus example.

this is in preparation for the master case, where you will have 2 types of devices, so need to check if the type is correct.
