amd64_edac: dump DIMM sizes on K8 too

Extend f10_debug_display_dimm_sizes to dump the logical DIMMs
configuration on K8 revF too. Remove the ganged arg since we print the
DCT operating mode (ganged vs unganged) earlier.

Also, DCT csrow configuration is relevant therefore dump it as
KERN_DEBUG instead of only on debug builds. Remove misleading DIMM
output since there's no reliable way of mapping of chip selects to
actual physical DIMMs.
