sof-soundwire: Correct the PCM device for cs35l56 bridge speakers

Browse source 
In the case the speaker amps are connected through the codec the current
routing is hijacking the headphone PCM device and using that. It would
be better to use the dedicated speaker PCM device. Update the PCM and
the routing to match.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/778
