A commit fcd164e622 ("Permit to PCM plug configuration to specify unchanged
parameters. Added support for RT signals to async interface. Added ops for
PCM mix.") added a pair of NORMS_LABELS/NORMS_END, however they have been
no longer used.
This commit removes them in a point to reduce the amount of code to
maintain.
