mc146818rtc: add "rtc-time" link to "/machine/rtc"
Add a link to rtc under /machine providing a stable location for management apps to query the value of the time. The link should be added by any object that sends RTC_TIME_CHANGE events. {"execute":"qom-get","arguments":{"path":"/machine","property":"rtc-time"} } Suggested by Paolo Bonzini and Andreas Faerber.
