    dimm: Implement pseudo device driver for DIMM related drivers
    
    - This pseudo device driver installs sensor device for DIMM related
      sensors (memtemp(4) and upcoming ecc(4) changes).
    - This pseudo device driver keeps DIMM location information.  And
      the location information is exposed through a new sysctl tree,
      hw.dimminfo.  The nodes in this sysctl tree have the same names
      as the sensor devices, so that programatic way could be used to
      report DIMM status.
    - This pseudo device implements common sensor update function for
      memtemp(4).  And it keeps configurable temperature thresholds for
      memtemp(4) sensor.
    - Utilize this pseudo device driver in memtemp(4).
