ALSA: hda - don't create dysfunctional mixer controls for ca0132

commit c41999a23929f30808bae6009d8065052d4d73fd upstream.

It's possible that these amps are settable somehow, e g through
secret codec verbs, but for now, don't create the controls (as
they won't be working anyway, and cause errors in amixer).
