Fix mic not working during call when Speaker is on

- swapped mux values to match TX7 setting of the DMIC Enfire config in
  Speaker DMIC Endfire config
- not sure if this is the definite fix; i have a hunch that currently
  only one of the mics is working, this simply routes the working mic
- still, mic works in speaker mode so meh...

Disable screen wake for Menu and Back keys

- as S4 active has hardware keys, menu and back wake screen
- this option is inconsistent especially when home-wake has
  been disabled
