Remove obsolete links to softmixer controls

Remove obsolete links to playbacks/captures softmixer controls.
These links are not used anymore (only 'halmap' controls are used).
It also means that references to controls in 'halmixer' section
of json configuration files must be removed (as it's done for example
json configuration file in this commit).

BUG-AGL : SPEC-2329
