m68k/mac: Enable RTC for 100-series PowerBooks

Browse source

According to Apple's Developer Notes, all of the early PowerBook models
have their RTC connected to VIA1. Use the VIA clock ops as appropriate.
This was tested on a PowerBook 170.

Don't use the VIA ops when not appropriate. Calling unimplemented clock
or PRAM getter or setter ops can now result in an error instead of
failing silently.
