Driver must implement this function and add dev_attr_parent_trigger
in their trigger attribute group to be able to use parent trigger
feature.

version 2:
- add comment about parent trigger usag
various ways.
To be able to select them "slave_mode" attribute is added to STM32 triggers.
For example the combinaison of parent_trigger and slave_mode allows to start
a trigger only when parent trigger level is high or to reset it on parent
trigger rising edge.
