[PATCH 0/2] qapi: Move RTC_CHANGE back out of target schema

[Peter Maydell <peter.maydell@linaro.org>]

This patchset moves RTC_CHANGE back to misc.json, effectively
reverting commit 183e4281a30962, which moved the RTC_CHANGE event to
the target schema.  That change was an attempt to make the event
target-specific to improve introspection, but the event isn't really
target-specific: it's machine or device specific.  Putting RTC_CHANGE
in the target schema with an ifdef list reduces maintainability (by
adding an if: list with a long list of targets that needs to be
manually updated as architectures are added or removed or as new
devices gain the RTC_CHANGE functionality) and increases compile time
(by preventing RTC devices which emit the event from being "compile
once" rather than "compile once per target", because
qapi-events-misc-target.h uses TARGET_* ifdefs, which are poisoned in
"compile once" files.)

Patch 2 fixes a minor documentation issue that I noticed while
I was doing this -- we didn't document that the units used in
the RTC_CHANGE event are seconds.

thanks
