[PATCH EDAC v26 36/66] i5400_edac: improve debug messages to better represent the filled memory

[Mauro Carvalho Chehab <mchehab@xxxxxxxxxx>]

Improves the debug output message, in order to better represent the
memory controller hierarchy, when outputing the debug messages.

No functional changes when debug is disabled.
