EDAC, amd64: Rework messages in ecc_enabled()

Browse Source 
Print the node number when informing that DRAM ECC is disabled so
that we can show which nodes have DRAM ECC disabled. Also, print more
detailed system information as edac_dbg(), so as to not bother general
users.

Switch amd64_notice to amd64_info to match the message above it.
