ALSA: hda/cs8409: Suppress vmaster control for Dolphin models

Browse Source 
commit a2ed0a44d637ef9deca595054c206da7d6cbdcbc upstream.

Customer has reported an issue with specific desktop platform
where two CS42L42 codecs are connected to CS8409 HDA bridge.
If "Master Volume Control" is created then on Ubuntu OS UCM
left/right balance slider in UI audio settings has no effect.
This patch will fix this issue for a target paltform.
