[SRU][J/L/M][PATCH 1/1] ALSA: hda/cs8409: Suppress vmaster control for Dolphin models

[Hui Wang]

From: Vitaly Rodionov <vitalyr at opensource.cirrus.com>

BugLink: https://bugs.launchpad.net/bugs/2051050

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.
