drivers: sensor: Store sensor trigger structure reference for client use

Browse source 
Store sensor trigger structure reference provided on `trigger_set`, and
pass reference back to client when trigger callback is invoked.

This will enable client to use `CONTAINER_OF()` inside its trigger
callback code.
