Log Message:
Add proper RealTime Clock support for HP9000/425e.

As the OpenBSD/hp300 page says 425e doesn't have the traditional
RTC at intio (as it also lacks DCA 16550 serial at intio?),
but after a few hour investigation it turns out that
425e uses mc146818 compatible calendar clock in
the Apollo "frodo" utility chip and the frodo chip on
425e actually has the 32kHz OSC and is actually backed up
by the onboard lithium battery.

Tested on HP425e (with mcclock) and HP362 (with old rtc).
