Nobody(*) uses them.  Dropping this will allow us to make the total
number of memory controllers configurable (as we won't have to
worry about duplicated device names under this directory).

Boris: Apply this, then your earlier patch to get rid of the
hard coded limit on the number of memory controllers:
  https://marc.info/?l=linux-edac&m=153797567628947&w=2
the combination works on my 4 socket machine. Perhaps HPE
can test on their superdome.
