of: overlay: unittest: add tests for overlay notifiers
Add tests for overlay apply and remove notifiers. Trigger errors
for each of the notifier actions.
These tests will reveal a memory leak problem when a notifier returns
an error for action OF_OVERLAY_POST_APPLY. The pr_err() message is:
OF: ERROR: memory leak, expected refcount 1 instead of 3,
of_node_get()/of_node_put() unbalanced - destroy cset entry: attach
overlay node /testcase-data/overlay-node/test-bus/test-unittest17
