tools: topology2: change deep buffer speaker PCM name for SDW

Change the PCM name for deep buffer speaker from to
"Deepbuffer Speaker". This only affects one shipping topology file
sof-ptl-rt712-l3-rt1320-l3-4ch.tplg.

After this change, the naming is more consistent:

 - Jack Out
 - Speaker
 - Deepbuffer Jack Out
 - Deepbuffer Speaker
