soundwire: enable Data Port test modes
Test modes are required for all SoundWire IP, and help debug integration issues. In theory each port can be configured with a different mode but to simplify this patch only offers separate configurations for the Master and Slave ports - this covers 99% of the intended cases during platform integration. The test mode value is set via platform-specific ways.
