Log Message:
Allow MD code to provide functions for reading/writing NVRAM/RTC
locations. If passed NULL, the old behaviour using bus_space_{read,write}_1()
is used. Otherwise, all access to the chip goes via the MD functions.

This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is not
directly addressable.
