sound-soc: Custom sound control

Based on Boeffla sound (Andip71) with rewrite of sysinterface and code refactoring.
sound-control: Fix band input and circumvent call detection
sound-control: Throw out several state variables, add new detection methods

Camera microphone levels with help of new MHS.
Further code cleanup and refactoring.
sound-control: Equalizer, mono fixes and branch prediction
Boeffla-Sound: Engine 1.6.0
Boeffla Sound: FM radio not available with LTE models

set #ifdef conditional to disable unused logic

Credits to faux123 for the proper exclusions using #ifdefs instead of just removing the FM radio related code
