topology2: cavs-nocodec-multicore.conf: Rename playback volumes

Rename SSP0, SSP1, and SSP2 playback volumes according to PCM names
they are connected to. Define the PCM names as variables so the name
can be changed in a single place.

This is how the change will look like:

'gain.1.1 Playback Volume 1' to
'gain.1.1 Pre Mixer Port0 Playback Volume'

'gain.14.1 Main Playback Volume 14' to
'gain.14.1 Post Mixer Port0 Playback Volume'

'gain.3.1 Playback Volume 3' to
'gain.3.1 Pre Mixer Port1 Playback Volume'

'gain.4.1 Main Playback Volume 4' to
'gain.4.1 Post Mixer Port1 Playback Volume'

'gain.5.1 Playback Volume 5' to
'gain.5.1 Pre Mixer Port2 Playback Volume'

'gain.6.1 Main Playback Volume 6' to
'gain.6.1 Post Mixer Port2 Playback Volume'
