iio: ABI: stm32-timer-trigger: Fuse unusual ABI into main doc.
We can't duplicate the description of sampling_frequency. This device
has some unusual requirements which we solved by giving a
sampling_frequency of 0 special meaning. As such add a note
about this unusual usage to the main documentation.
Whilst I don't particularly like this resolution, it is the best
I could come up with given earlier discussion on this topic.
