Condat audio_Init(): rm setting of sidetone level The default sidetone level in the absence of audio mode loading is just that, a basic default without any promises of good tuning. In the original TCS211 code this default sidetone level was set in two places: first in L1 init of ABB-via-DSP registers (set to -17 dB), and then initialized again in Condat audio_Init(), this time set to -5 dB. The present change removes the redundant second initialization. The default sidetone level is now -17 dB instead of -5 dB with this change, but again it is just the default; all serious users are now expected to use audio mode config files.
