sof-soundwire: Add support for cs42l43/cs35l56 bridge configuration

Browse source 
The cs42l43 has both a SPI master and an I2S interface, in some
configurations 2 cs35l56 amplifiers are connected to these to provide
bass speakers whilst the cs42l43's internal speaker drivers are used for
the tweeters. Add UCM configuration for this type of system.
