4a-mixer: use PREFERRED_RPROVIDER for virtual/mixer

This removes ambiguity on the mixer choice when 4A is enabled.

The warning seen at the beginning of bitbake also disappears:
------
NOTE: Multiple providers are available for runtime virtual/mixer (4a-mixer, mixer)
Consider defining a PREFERRED_RPROVIDER entry to match virtual/mixer
------

Bug-AGL: SPEC-1520
