  Log:
  o Sync with the NetBSD mk48txx driver (the result simplyfies some changes
    I have in mind for the genclock interface):
    - Recognize the MK48T18 as well (differs from the MK48T08 only in
      packaging options and voltages).
    - 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.
    - Cleanup MI mk48txx(4) todclock driver:
      - Prepare mk48txxvar.h and leave only register definitions in
        mk48txxreg.h.
      - Define struct mk48txx_softc as usual devices and allocate necessary
        members in it.
      - Change mk48txx_attach() to only take a device_t.
  o While converting the sparc64 eeprom driver to the above changes:
    - Remove some dead code and stale comments.
    - Use the NVRAM size provided by the mk48txx driver instead of hardcoding
      it as suggested by a comment.
    - Add a comment about why it doesn't make much sense to read the hostid
      directly from the NVRAM except for displaying it when attaching.
    - Don't print the hostid if it reads all zero because it's stored
      elsewhere.
