Many soc-camera hosts do that.

These are not the features, that we _have_ to implement, these are just
the ones, that are related to the snapshot mode:
* flash strobe (provided, we do not want to control its timing from
generic controls, and leave that to "reasonable defaults" or to
private controls)
* trigger pin / command
* external exposure
* exposure mode (ERS, GRR,...)
* use "trigger" or "shutter" for readout
* number of frames to capture
