pseries: Export RTC time via QOM
On x86, the guest's RTC can be read with QMP, either from the RTC device's
"date" property or via the "rtc-time" property on the machine (which is an
alias to the former). This is set up in the mc146818rtc driver, and
doesn't work on other targets.
This patch adds a similar "date" property to the pseries machine's RTAS RTC
and adds a compatible alias to the machine.
