EDAC/amd64: Set grain per DIMM
[ Upstream commit 466503d6b1b33be46ab87c6090f0ade6c6011cbc ]
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.
Fixes: 3724ace582d9 ("EDAC/mc: Fix grain_bits calculation")
