a "real" driver to have priority.
Make sure that a todclock service does exist before trying to read and
write the time.
If no RTC read routine exists, just use the suggested time in inittodr().

inittodr() and resettodr() functions and is designed to be a child
device of an RTC device. This allows one of multiple RTC's attached
to be used to provide the basic time of day functions.
