EDAC: Introduce an mci_for_each_dimm() iterator
Introduce an mci_for_each_dimm() iterator. It returns a pointer to
a struct dimm_info. This makes the declaration and use of an index
obsolete and avoids access to internal data of struct mci (direct array
access etc).
[ bp: push the struct dimm_info *dimm; declaration into the
CONFIG_EDAC_DEBUG block. ]
