sof-soundwire: Change map control names to make them unique and user friendly

Both 'Speaker Digital' and 'cs42l43 PDM2' names were found in other alsa
controls, confusing the MixerElems paths. Make them unique to avoid errors for
hardware mutes. Also add 'Capture' string into microphone controls to make
them work properly.
