amd64_edac: Carve out ECC-related hw settings
This is in preparation for the init path reorganization where we want only to 1) test whether a particular node supports ECC 2) can it be enabled and only then do the necessary allocation/initialization. For that, we need to decouple the ECC settings of the node from the instance's descriptor. The should be no functional change introduced by this patch.
