This is a large patch to refactor the original EDAC module in the kernel
and to break it up into better file granularity, such that each source
file contains a given subsystem of the EDAC CORE.

Originally, the EDAC 'core' was contained in one source file: edac_mc.c
with it corresponding edac_mc.h file.

Now, there are the following files:

edac_module.c	The main module init/exit function and other overhead
edac_mc.c	Code handling the edac_mc class of object
edac_mc_sysfs.c	Code handling for sysfs presentation
edac_pci_sysfs.c  Code handling for PCI sysfs presentation
edac_core.h	CORE .h include file for 'edac_mc' and 'edac_device' drivers
edac_module.h	Internal CORE .h include file

This forms a foundation upon which a later patch can create the 'edac_device'
class of object code in a new file 'edac_device.c'.
