The POWERDOWN event was first documented in 0aab9ec3. But since
dfab4892 later restored this file to the state prior to qmp events,
and we never documented it in the past, anyone using this file
instead of qapi will miss out on this event. Tweak the existing
wording of SHUTDOWN to match 84321831, and make the difference
between the two events apparent.
* docs/qmp/qmp-events.txt (POWERDOWN): Add.
(SHUTDOWN): Tweak.
