Subject: [PATCH 14/18] EDAC/amd64: Add setup_mci_misc_attrs() into pvt->ops

From: Muralidhara M K <muralidhara.mk@....com>

GPU Nodes will expose the memory controller attributes differently than
current systems. A function pointer should be used rather than introduce
another branching condition.

Prepare for this by adding setup_mci_misc_attrs() to pvt->ops. Legacy and
modern systems use the same function. A new function will be added for
GPU Nodes.
