[Fix] For 1), add proper PCM stream assignment to the rear microphone. For 2), add MixerElem to let alsa-lib and PulseAudio to pick correct mixer to change HW gain. [Test] With the new UCM applied, rear mic starts to work, and PulseAudio can control the hardware gain. [Regression Potential] The system hasn't hit the market so there's no chance to regression any system in the wild.
