[PATCH 0/1][SRU][L/OEM-6.0] Microphone mute LED not working after pressing the mic mute hotkey

[Chris Chiu]

BugLink: https://bugs.launchpad.net/bugs/2000909

[SRU Justification]

[Impact]
Mic mute LED can't be toggled by the state of the mic-mute hotkey.

[Fix]
Create a new fixup to address the dual codec problem on particular platforms.

[Test Case]
Use the following command and check there's no duplicate mixer with the same name `Capture Switch`, `Capture Volume`
   $amixer controls

[Where problems could occur]
The commit only applies dual codec fixup on particular affected models.
Should be no regression problem or any side effect to generic platforms.
