Add support for BT Soundwire port configurations. Add support for flow control modes for fractional channel rates. Configure slave side data ports for flow controls modes. Fix the direction adn offset1 fields for Tx ports on BT Soundwire. When the flow control mode is not required, update the slave configuration accordingly. Sample Interval HIGH field in slave port controls needs to be reset to zero when Sample Interval value is less than 255. Avoid clock stop mode for bt swr slave during runtime suspend call. In case of fractional sampling rates, additional offset bits need to be added between samples to carry flow control information.
