The st_lsm6dsx_event_settings structure contains fields specific
for one event type (wakeup). In preparation for adding support for
more event types, introduce an event id enum and a generic event
source structure, and replace wakeup-specific data in struct
st_lsm6dsx_event_settings with an array of event source structures.
