INA3221 supports both continuous and single-shot modes. When
running in the continuous mode, it keeps measuring the inputs
and converting them to the data register even if there are no
users reading the data out. In this use case, this could be a
power waste.
So this patch adds a single-shot mode

The piece of information "who created a certain cftype" is not stored

This commit addresses this problem by adding a new field in the cftype
