EDAC: Drop duplicated array of strings for memory type names

Somehow we ended up with two separate arrays of strings to describe the
"enum mem_type" values.

In edac_mc.c we have an exported list edac_mem_types[] that is used
by a couple of drivers in debug messaged.

In edac_mc_sysfs.c we have a private list that is used to display
values in:
  /sys/devices/system/edac/mc/mc*/dimm*/dimm_mem_type
  /sys/devices/system/edac/mc/mc*/csrow*/mem_type

This list was missing a value for MEM_LRDDR3.

The string values in the two lists were different :-(

Combining the lists, I kept the values so that the sysfs output
will be unchanged as some scripts may depend on that.
