Add an offset parameter that can be passed in the periodic trigger.
This is useful for example when ADC drivers implement a separate periodic
signal to trigger conversion and need offload to read the result with
some delay. While at it, add some documentation to offload periodic trigger
parameters.

Add additional headers used in this driver. This is better than relying
on implicit includes via other unrelated headers.
Also sort the existing includes while doing so.
