audiomixer: add new channel volume API
- Add API to control left and right channel volumes.
- Fix a bug in treble gain update. The changed gain value of Treble is
not updated in the audiomixer as the gain changed
callback(on_eq_params_changed) doesnt look beyond bass for gain
controls. Fix this issue by continuing to look beyond bass control.
- Adjust the floating point comparision epsilon value from 0.000001 to
0.00001.
