r-car m2: preconfigure Porter/Koelsch sound mixer

Sound is inaudible when starting a Porter/Koelsch board,
because default state of their sound mixer is muted.

Add a "alsa-utils-config" recipe which will be commented
out, but available in local.conf, to preconfigure their
mixer. Sound volume will be approximately 25% of maximum.
