Subject: [PATCH] Revert "Fixes LRDIMM eff_config bugs"

This reverts commit 40a34c94a981ebfe9e1ff95263663cda0cbaaa42.

This broke p9dsu platforms with 16GB DIMMs.

We'd die in ISTEP 15.1 and come back with callouts like this:

*IF* you were lucky enough to IPL, you'd have a bunch of GARD records
for DIMMs that previously worked perfectly, as well as some runtime
memory errors:

Out of the three p9dsu systems I tried, the ones with 16GB DIMMs failed,
and the ones with 32GB DIMMs did not. FRU snippets:

So, for the moment, to not break existing hardware, revert the commit.
