edac_mc: Cleanup per-dimm_info debug messages
The edac_mc_alloc() routine allocates one dimm_info device for all
possible memories, including the non-filled ones. The debug messages
there are somewhat confusing. So, cleans them, by moving the code
that prints the memory location to edac_mc, and using it on both
edac_mc_sysfs and edac_mc.
Also, only dumps information when DIMM/ranks are actually
filled.
After this patch, a dimm-based memory controller will print the debug
info as:

(a rank-based memory controller would print, instead of "dimm?", "rank?"
on the above debug info)
