This is the next phase of ti-ads112c14 support after [1].

Some design decision notes:
* These chips do have a continuous mode for sampling, but since it would
  only allow for enabling a single channel at a time, we have
  implemented buffered mode using the single-shot mode instead. We
  may consider adding continuous mode support later if there is a need
  for it (e.g. a need for higher sampling rates). It could be a bit
  complicated to do that though because it also changes timings. The
  timing issues will be discussed more in some later patches for adding
  settling time support.
* We wanted to enable CRC checking for data integrity, so it is just
  always enabled. This way, the buffer layout is always the same. I
  don't think we have an existing control for toggling CRC checking
  anyway.
