Alexander Leidinger 34ac5f0f5f * Fixed rate operation for es1370 chip to solve conflicting 
sampling rate between playback and recording. This can be
  disabled / enabled via kernel hints
  (hint.pcm.<unit>.fixed_rate=0/4000-48000) or sysctl
  hw.snd.pcm<unit>.fixed_rate=0/4000-48000). Default to 48khz
  fixed rate. [1]
* Basic cleanup. *_es1371x_* -> *_es137x_*.
* Some locking fixes. [2]
