Update non-present dimm/ocmb i2c attributes

The dimm/ocmb i2c information should match up, especially for the
VPD_PRIMARY attribute. Also we had a problem where the settings we
had for the dimm target was getting targets that were not present
in the simics model showing up present to hostboot. By forcing targets
we no should not show up to have invalid devAddr fields set in the
attribute, we avoid having targets show up when they should not.
