Enable 2ND mic on OMI CV1 ($500)

[beastoin]

Objective: Having better audio quality on Omi CV1

Key results:

• Enable the second mic of OMI CV1; currently, only one mic is activated.
• Fix the mic gain issue on OMI CV1; you should record the audio by using Devkit 2 and OMI CV1 to see the difference, but keep focus on OMI CV1 and maximize its mic audio quality.
