On suspend/resume save the current time to the RTC earlier and restore it later
so that the very long delay operations do not slow the clock unnecessarily.
Add early support for hw.setperf and hw.cpuspeed for zaurus, it appears
to be able to run at 91MHz and 209MHz as well as the std 416MHz with this
change. Hopefully it is doing the speed changes correctly.
