Yazen Ghannam 466503d6b1 EDAC/amd64: Set grain per DIMM
The following commit introduced a warning on error reports without a
non-zero grain value.

  3724ace582d9 ("EDAC/mc: Fix grain_bits calculation")

The amd64_edac_mod module does not provide a value, so the warning will
be given on the first reported memory error.

Set the grain per DIMM to cacheline size (64 bytes). This is the current
recommendation.
