FS#10569 RTC driver cleanup
Change the RTC drivers so that the rtc_(read|write)_datetime functions now deal directly with the tm struct instead of passing a string of bcd digits to/from (set|get)_time .
This simplifies drivers for rtc's that do not use a bcd representation internally and cleans up some target specific code and #ifdefs in generic code. Implement simple stubs for the sim to avoid #ifdefing for that too.
